  • Chapter 12 Voice Modes
    Modulation Sources (What and How We Communicate) 12 odulation Sources”—what does that mean? An engineer might simply call this chapter Baseband. Engineers use that term to distinguish information before it’s used to modulate “M a carrier. So, this chapter covers the various kinds of information we impress on RF (audio, video, digital, remote control) before that information has been moved to some intermediate frequency (IF) or the desired RF. Baseband carries the connotation “at or near dc” because the final RF is usually much higher than the baseband frequency, yet that is misleading. For example, a baseband ATV signal usually extends up to 5 MHz, which is hardly dc. Nonetheless, compared to the operating frequencies (52 to 806 MHz for broadcast, 420 MHz and higher for amateur) it is practically dc. Here we will discuss characteristics of the information (such as bandwidth), how we prepare it for transmission, optimize the transfer and process it after reception. Nearly all of the processing discussed in this chapter can be implemented with the emerging digital- signal-processing (DSP) technology. For example, the CLOVER-II system described later in this chap- ter uses DSP to vary the modulation scheme as required by propagation conditions. Look to the Digital Signal Processing chapter for further information about DSP techniques. BANDWIDTH Whenever information is added to a carrier (we say the carrier is modulated), sidebands are produced. Sidebands are the frequency bands on both sides of a carrier resulting from the baseband signal varying some characteristic of the carrier. The modulation process creates two sidebands: the upper sideband (USB) and the lower sideband (LSB).

  • GV-698 Manual
    TV SIGNAL GENERATOR GV-698 1 GENERAL 1.1 Description The GV-698 TV signal generator is a multi-standard, multi-system unit with advanced functions. It has been designed using the most modern technology resulting in great reliability and reduced consumption. Its modular structure makes it highly versatile and permits rapid access to all its components. Starting from base modules, it is possible to increase the applications of the instrument by adding modules if desired. The GV-698 is particularly suitable for those industrial sectors that require high-quality pictures such as adjustment and analysis lines, production studios, technical assistance services, etc. In addition, being easy to operate, it is indispensable in the training of video technicians. The GV-698 operates in accord with the CCIR/OIRT recommendations for the colour systems PAL-SECAM and FCC for the NTSC system and may provide a modulated signal for practically all the transmission standards presently in use. The video is equipped with 32 pattern charts to analyze the picture visually or with an oscilloscope. For geometric adjustments, the electronic circle can be inserted in all the charts. To detect defects in the tuning circuits and IF amplifier stages, the GV-698 has a complete radio-frequency modulator, its principal characteristics being: - Frequency range from 37 to 865 MHz - Synthesized frequency output - Tuning by channels or by frequency (in steps of 50 kHz) - Attenuation of output RF signal up to 50 dB (in steps of 10 dB) The VTR (Video Text Recorder) function is available to check the functioning of video tape recorders, particularly the functions of "still", stepped image, heads position, etc.

  • Analog Video Encoding Formats Ntsc
    ANALOG VIDEO ENCODING FORMATS NTSC NTSC is the analog television system in use in the United States and many other countries, including most of the Americas and some parts of East Asia. It is named for the National Television System(s) Committee, the industry-wide standardization body that created it. Analog television encodes picture information by varying the voltages and/or frequency of the signal. ... The Americas refers collectively to North and South America, as a relatively recent and less ambiguous alternative to the name America, which may refer to either the Americas (typically in languages other than English, where it is often considered a single continent) or to the United States (in English and...East Asia can be defined in either cultural or geographic terms. ... History The National Television Systems Committee was established in 1940 by the Federal Communications Commission (FCC) to resolve the conflicts which had arisen between companies over the introduction of a nationwide analog television system in the U.S. The committee in March 1941 issued a technical standard for black and white television. This built upon a 1936 recommendation made by the Radio Manufacturers Association (RMA) that used 441 lines. With the advancement of the vestigial sideband technique for broadcasting that increased available bandwidth, there was an opportunity to increase the image resolution. The NTSC compromised between RCA's desire to keep a 441-line standard (their NBC TV network was already using it) and Philco's desire to increase it to between 600 and 800, settling on a 525-line transmission. 1940 was a leap year starting on Monday (link will take you to calendar).

We show you ways to make the required measurements, and why The NCTA and the cities have they are important. In additional, we will recently agreed to, among other things, a set discuss some of the problems we have of basic measurements to be made on video observed in cable systems. signals. We'll show you how to make the new measurements, and tell you what they THE NEW MEASUREMENTS mean. We'll also discuss other basic REQUIRED measurements that should be made in order to provide good signals. The measur.ement The cable industry and the cities have emphasis is on practical things that can be recently reached agreement on, among other done in the headend, using available things, technical performance standards for equipment augmented with devices that can cable systems.

  • MC44CC373 CMOS Audio/Video RF Modulators
    Freescale Semiconductor Document Number: MC44CC373 Rev 3.2, 04/2009 CMOS Audio/Video RF Modulators The MC44CC373 / MC44CC374 CMOS family of RF modulators is the latest MC44CC373CA generation of the legacy MC44BS373/4 family of devices. MC44CC373CAS The MC44CC373/MC44CC374 RF modulators are designed for use in VCRs, set-top boxes, and similar devices.They support multiple standards, and can be MC44CC374CA programmed to support PAL, SECAM, or NTSC formats. The devices are programmed by a high-speed I2C Bus. MC44CC374T1A A programmable, internal PLL, with on-chip LC tank covers the full UHF range. The modulators incorporate a programmable, on-chip, sound subcarrier oscil- lator that covers all broadcast standards. No external tank circuit components CMOS AUDIO/VIDEO are required, reducing PCB complexity and the need for external adjustments. RF MODULATORS The PLL obtains its reference from a low cost 4 MHz crystal oscillator. The devices are available in a 16-pin SOIC, Pb-free package. These parts are functionally equivalent to the MC44BS373/4 series, but are not direct drop-in re- placements. All devices now include the AUXIN found previously only on the 20-pin pack- age option of the MC44BS373. This is a direct input for a modulated subcarrier and is useful in BTSC or NICAM stereo sound or other subcarrier applications. The MC44CC373CASEF has a secondary I2C address for applications using 2 EF SUFFIX two modulators on one I C Bus. SOIC-16 PACKAGE CASE 751B-05 Features • Multi-TV standard support: NTSC, PAL, SECAM (B/G, • Auxiliary input bypasses AM/FM modulators for I, D/K, L, M/N).
