FM Stereo Format 1

We have seen how frequency modulation can be used to encode a signal. But for stereo you need two signals. How can you put two signals on an electromagnetic wave? The answer is that you actually combine more than one wave. The FM broadcast for a stereo signal from a commercial radio station is actually fairly complicated. It contains a frequency modulated carrier wave that is modulated with the left plus right channel audio signals. In addition,

The AM modulated carrier is modulated with left-right signal. An older mono receiver would play only the left + right signal. The stereo receiver would get the L+R and L R signals and use them to produce L and R separately. These were then sent to the two speakers. Finally, another signal is added at 19 KHz above the FM modulated carrier. This signal, called a pilot signal, makes the receiver aware that this is a stereo broadcast. The EM wave from and FM stereo station is complicated to look at in time domain, but in frequency domain it is easier to understand. Figure 1 shows a sketch of the FM radiostation EM wave versus frequency.

3 The Great Rose Bowl Hoax 04/13/2006 05:07 PM

The Great Rose Bowl Hoax January 2, 1961: a capacity crowd filled the Rose Bowl > > Click here for Tickets! < < stadium to watch the Minnesota Golden Gophers take on the in the New Year's Day game (played that year on January 2 because the 1st fell on a Sunday). Millions more watched around the nation, crowded in front of tv sets in living rooms, restaurants, and bars.

NBC was providing live coverage of the game. At the end of the first half the Huskies led 17 to 0, and everyone settled in to watch the half-time show for which the Washington marching band had prepared an elaborate flip- card routine.

Sets of variously colored flip cards and an instruction sheet had been left on seats in the section of the stadium where the Washington students were located. When the students heard the signal from the cheerleaders, they were each supposed to hold up the appropriate flip card (as designated by the instruction sheet) over their head. In this way different gigantic images would be formed that would be visible to the rest of the stadium, as well as to those viewing at home. The Washington band planned on displaying a series of fifteen flip-card images in total.

The flip-card show got off to a well-coordinated start. Everything went smoothly, and the crowd marvelled at the colorful images forming, as if by magic, at the command of the cheerleaders. It wasn't until the 12th image that things began to go a little wrong. This image was supposed to depict a husky, Washington's mascot. But instead a creature appeared that had buck teeth and round ears. It looked almost like a beaver.

The next image was even worse. The word 'HUSKIES' was supposed to unfurl from left to right. But for some reason the word was reversed, so that it now read 'SEIKSUH'.

These strange glitches rattled the Washington cheerleaders. They wondered if they might have made some careless mistakes when designing the complex stunt. But there was nothing for them to do about it now except continue on, and so they gave the signal for the next image.

What happened next has lived on in popular memory long after the rest of the 1961 Rose Bowl has been forgotten. It was one of those classic moments when a prank comes together instantly, perfectly, and dramatically.

The word 'CALTECH' appeared, held aloft by hundreds of Washington students. The name towered above the field in bold, black letters and was broadcast out to millions of viewers nationwide.

For a few seconds the stadium was plunged into a baffled silence. Everyone knew what Caltech was. It was that little Pasadena technical college down the road from the Rose Bowl stadium. What no one could figure out was what its name was doing in the middle of Washington's flip-card show. Throughout the United States, a million minds simultaneously struggled to comprehend this enigma.

In fact, only a handful of people watching the game understood the full significance of what had just happened, and these were the Caltech students who had labored for the past month to secretly alter Washington's flip-card show.

The idea for the prank had arisen out of the indignation that a group of Caltech students (who would come to be known as the "Fiendish Fourteen") felt at Caltech's lack of representation at the Rose Bowl's famous New Year's Day game. After all, the Rose Bowl stadium was right in Caltech's backyard, and the Caltech team often played there. But every year the technical college, despite its many merits, was entirely ignored in the hype building up to the game. This group of students decided to rectify the situation. They determined to make sure that Caltech got some recognition at the upcoming game, and Washington's flip-card show seemed to be the perfect vehicle for achieving their goal.

Pulling off the prank required obtaining a detailed knowledge of how Washington's flip-card system worked.

http://www.museumofhoaxes.com/pranks/rosebowl.html Page 1 of 3 The Great Rose Bowl Hoax 04/13/2006 05:07 PM

This knowledge was acquired simply by asking Washington's head cheerleader to explain it to them. Of course, the cheerleader was under the impression that he was explaining the system to a curious reporter from a local Los Angeles high school. What he didn't know was that the reporter was actually a Caltech student in disguise.

What the Fiendish Fourteen discovered was that to alter the show it would simply be necessary to change what was written on the instruction sheets that would be left on the seats—all 2,232 of them—blocked off for the Washington fans. This was a daunting task, but the Fiendish Fourteen were up to it.

They staked out the hotel where the Washington cheerleaders were staying. When the cheerleaders were away they broke into their rooms and removed a single instruction sheet. This they took to a printer and had him print up 2,232 exact duplicates. A moment of panic occurred when it was realized that the new sheets looked conspicuously less worn than the old ones. But it was decided that since the sheets would be replaced en masse, this lack of aging might not be noticed.

Then each sheet had to be individually marked up by hand according to Caltech's new master plan, so that the seat numbers and card designations would be correct. This was done all in one marathon session on New Year's Eve at Lloyd House, the home of the Fiendish Fourteen. When the task was done, three students were dispatched back to the hotel of the Washington cheerleaders to switch the old sheets with the new, altered ones. The cheerleaders, as was known beforehand, were away from their rooms visiting Disneyland. The switch completed successfully, the Fiendish Fourteen sat back and nervously waited for their scheme to come to fruition.

Luck was on their side, and all the elements of the plan came together better than they had imagined possible. The first eleven images of the flip-card show had been left basically unaltered, to allay suspicion. The first real alteration occurred with the 12th image, which had been changed from a husky to a beaver, Caltech's mascot. This change was subtle enough that it escaped the attention of most of the game's audience. The 13th image had been flipped so that it read 'SEIKSUH' instead of 'HUSKIES'. The Fiendish Fourteen knew that viewers would chalk this up to simple error. But these changes were a mere build-up to the 14th image, the unveiling of 'CALTECH' itself.

At the moment when Caltech's name unfurled across the stadium, NBC's cameras were focused directly on the flip-card show, providing the best possible vantage point for viewers across the nation to watch the ensuing drama. Washington's band, upon seeing the gigantic rogue name leering down at them from the stands, immediately stopped playing, and silence descended on the stadium. Even the television announcers were momentarily speechless. For a few seconds this silent tension enveloped the entire stadium. Finally the significance of what had just happened began to sink in, and then the laughter began.

Infuriated, the Washington band marched off the field, refusing to give the signal for the 15th, and final, image (which unbeknownst to them had been left unaltered). Gradually the laughter died down and the game continued. The Washington team managed to maintain its lead during the second half but didn't score any more points. The final score was 17-7.

To this day the Great Rose Bowl Hoax, as it was soon dubbed, remains one of the best known college pranks ever perpetrated. The Museum of Hoaxes concurs with the judgement of Neil Steinberg, author of the classic study of college pranks If At All Possible Involve a Cow: The Book of College Pranks, that "few college pranks can be said to be more grandly conceived, carefully planned, flawlessly executed, and publicly dramatic" than the Rose Bowl Hoax.

It was the sheer public spectacle of the prank that set it apart—that it was staged not just at a college football game, but at the nationally televised Rose Bowl, probably the most famous annual college football game of all. Added to this was the universal admiration at the skill with which the prank was pulled off.

The success of the Rose Bowl Hoax threw down the gauntlet for future generations of Caltech students. In 1984 a group of them rose to the challenge when they managed to hack into the Rose Bowl stadium's electronic scoreboard system and began posting rogue messages during that years New Year's Day game. While technically more sophisticated than the first Rose Bowl hoax, this second hoax lacked the sheer shock value that the first one achieved.

For all these reasons, the Great Rose Bowl Hoax deservedly earns top place in the Museum's list of the Top Ten College Pranks ever.

1961 CHEVROLET IMPALA 'SUPER SPORT' CONVERTIBLE

BY 1961, CHEVROLET WAS NOT JUST SATISFIED WITH SELLING MILLIONS OF CHEVROLETS. THEY DECIDED TO FINE TUNE THEIR PERFORMANCE IMAGE AND BOOST SALES FURTHER BY OFFERING A "SUPER SPORT" PACKAGE . THE "SS" PACKAGE WAS REVEALED LATE IN THE MODEL YEAR INITIALLY, AS A WAY OF INTRODUCING SHOWROOM CUSTOMERS TO THE "ALL NEW" LATE ENTRY, 409 ENGINE OPTION. THE 409 WAS BASICALLY JUST A BORED OUT 348 BUT, IT QUICKLY BECAME KNOWN AS "THE TRUCK ENGINE DESIGNED FOR DRAG RACING AND STOCK CAR RACING". AFTER ONLY 142 ENGINES WERE ISSUED, PRODUCTION PROBLEMS, WITH THE HEADS WARPING, HALTED THE 409 OPTION SO, MOST OF THE "SS's" WERE NOT EQUIPPED AS 409'S. AS IT IS, ONLY 453 SUPER SPORTS WERE EVER BUILT AND ONLY A HANDFUL WERE CONVERTIBLES. THE FACTORY ORDERED 'KIT' ( FOR THE LACK OF A BETTER TERM ) REQUIRED AT LEAST A 348 C.I. MOTOR AND FOUR SPEED ( ALTHOUGH SOME 348/ 305 H.P. LESS DESIRABLE POWERGLIDES WERE BUILT). THE SUPER SPORT PACKAGE REQUIRED S.S. I.D. PLATES, HEAVY DUTY SPRINGS, SHOCKS, POWER STEERING & SINTERED METALLIC BRAKES. LET'S NOT FORGET THOSE GORGEOUS SPINNER HUBCAPS, PADDED DASH, 7,000 R.P.M. STEERING COLUMN MOUNTED TACH AND NARROW WHITEWALL TIRES ( NOT THE WIDE WHITEWALL TIRES SEEN ON OUR CAR). DEALERS ONLY CHARGED A PALTRY $63.10 FOR THE "SS PACKAGE" BUT, THE 'OPTIONS REQUIRED' HAD THE CAR 'STICKER OUT' AT OVER $4,000 ( MORE THAN THE BASE STICKER FOR A NEW CORVETTE !). OUR CAR IS FINISHED IN JEWEL BLUE W/ MATCHING INTERIOR AND WHITE SOFT TOP. SHE'S ALSO GOT F/R BUMPER GUARDS WITH REMOTE HOOD OPENER, DUAL MIRRORS, REAR ANTENNAE, THE ORIGINAL PUSHBUTTON 'CHEVY' AM RADIO AND 'INAPPROPRIATE' WIDE WHITEWALL TIRES (ORIGINALLY HAD NARROW http://www.classicdreamcars.com/61IMPALA.html Page 1 of 3 1961 CHEVROLET IMPALA SUPER SPORT CONVERTIBLE 04/13/2006 05:10 PM

AM RADIO AND 'INAPPROPRIATE' WIDE WHITEWALL TIRES (ORIGINALLY HAD NARROW WALL TIRES THAT WERE REMOVED BY OUR CUSTOMER) .IT HAS A COMPLETELY MATCHING NUMBER COMPONENT MOTOR, TRANMSISSION, REAR AND COLOR COMBINATION AND IS LOADED WITH THE SOLID LIFTER 348 / 4V, FOUR SPEED GEARBOX, POSITRACTION REAR. IT ALSO HAS IT'S ORIGINAL SHOWROOM BROCHURE AND MANUAL. MY SON AND I BOUGHT HER OFF THE FIELD AT AN A.A.C.A. CAR SHOW AT HERSHEY IN 1998. SOLD IT AS SOON AS WE GOT HOME... WE BOUGHT IT BACK FOUR YEARS LATER. OUR FAVORITE CAR AND NOT FOR SALE.

THE STORY:

Fifteen Hundred Cuban right-wing exiles, trained by the CIA, fumble an attempt to take over Cuba in the Bay of Pigs Invasion, 300 "Freedom Riders" risked death by riding a bus from Washington, DC to Birmingham Ala. to display 'the cause' of segregation, Audrey Hepburn made her screen debut in the film "Breakfast at Tiffany's", Judy Garland played Carnagie Hall, Eddie Murphy & Dan Marino were born while, Earnest Hemmingway and Gary Cooper ( actor) died. It all happened in 1961.

The first Super Sport is seen by many as the PUREST big Chevy muscle car ever built. The 1961 Impala was downsized that year and this added up to a small vehicle with a very large engine. Even with it's base engine V8 at 283 cubic inches, the '61 Chevy was viewed as a "barn burner". Once Chevrolet added the 409/360 H.P. late in the year, it was not uncommon to see 7.8 sec 0-60 and 15.8 sec. quarter mile runs. The 348 wasn't far behind in performance.

Chevrolet targeted customers who (quote) "like sports car flair teamed with big car elegance." This advertising babble started the Super Sport 'phenomenon' which continued for the next 35 years. Incredible as it may seem, the new Super Sport option could be ordered on an Impala convertible, two-door hardtop, two-door sedan and even a four door sedan. But in reality, most were ordered in two-door Sport coupes. All the buyer had to do was check-off the 'tick' marked "SS" and for $63.10 one got a bargain by any man's standards. Of course, the engine cost a bit more. V8's ran between $344 and $500. A recent factoid just uncovered: in order to order the 'Super Sport Package', one HAD to also order a Padded Dash, Narrow Wall Whitewalls( Black- Only-Wheels), Sintered Metallic Brakes, Positraction, Four-Speed ( Or Powerglide w/ the 348/305 only) and a Column- Mounted 7,000 r.p.m. Sun Tachometer. In effect, this drove the 'new' Super Sport to over $4,100, which was more than a new Vette. Hence, the low build.

Engines varied from the small horse 348/305 4V hydraulic lifter motor to the 348/280 Tri-Power to the solid lifter Special Turbo Thrust V8 version with 11:25:1 compression and 340 H.P. (4V). The lone 409 option pushed out 360 H.P. Although only 142 were ever offered due to production problems with the heads warping. The Four Speed gearbox was $188 and you automatically got a Special Shifter plate, mounted on the floor ( there was no special chrome console with the column shift automatic) . Chevy experts claim the 1961 Impala SS is the hardest to restore as original SS name plates, dash grab bar and floor shift plate are damn near impossible to find. This car is seen as the ultimate collectible as it is the first of the series that didn't end until 1996, when Chevy folded it's tent on the Super Sport nomenclature.

If the 1961 Super Sports were virtually unknown, the opposite was true of the 1962 version that followed. Over 99,000 1962 Super Sports were sold making this earlier edition the most rare. Our car was born in Farmington, Mass and was reported to be garaged 'all it's life'. Restored frame-off, all the panels are original. This beautiful Impala is a piece of muscle car history.
