  • Orban FMX Brochure
    www.SteamPoweredRadio.Com July 10, 1986 Dear Broadcaster: Thank you very much for your interest in OPTIMOD-FMX. Enclosed is a package of information from both Orban and CBS. I ' m sure you will find it interesting. In our articles, we explain why the Orban OPTIMOD- FMX will be substantially different and better than units offering only the CBS "developmental" design. Until IC chips become available, FMX receivers will be very scarce. The latest information from CBS is that the first chips will roll off the line during the summer of 1987 , permitting receivers to be available just prior to Christmas 1987 . Orban expects to begin accepting orders for OPTIMOD- FMX in the Fall, with deliveries beginning late i n the year. As we have more information available, we will s end it to you. If you have any additional questions, feel free to call me on our toll- free number: 800- 227- 4498. Thank you for your confidence in OPTIMOD- FMX .

  • A Theoretical and Experimental Study of Noise and Distortion in the Reception of Fm Signals
    A THEORETICAL AND EXPERIMENTAL STUDY OF NOISE AND DISTORTION IN THE RECEPTION OF FM SIGNALS Dr. Amar G. Bose Dr. William R. Short Professor of Electrical Engineering Research Staff, and Computer Science, M.I.T. Bose Corporation Presented at M.I.T. Jan. 25, 1989 Copyright ® 1989 Massachusetts Institute of Technology, Cambridge, MA 02139. Abstract A mathematical model is developed that can be used to analyze the effects of multipath on any modulation of an FM carrier. The predictions of this model are verified by simulation and by actual field testing. The model is used to analyze the existing FM stereo system and the proposed FMX system. The analysis, confirmed by field tests in over 15,000 locations, shows that FMX transmission significantly degrades reception on existing FM stereo receivers and that FMX receivers are inferior to FM stereo receivers for receiving FMX transmissions. i Table of Contents 1.0 Introduction 1 2.0 Objectives 1 3.0 The Multipath Model 1 3.1 Derivation of Error Due to Multipath 2 3.2 Observations from Examination of the Frequency Error 6 3.3 The Generation of Quadrature Modulation Signals by Multipath 8 3.4 Effects of Multipath on Phasing Errors in the Decoding of the 38 kHz Subcarrier 9 4.0 Quantitative Examination of Multipath-generated Errors in the Time and Frequency Domains 11 4.1 Review of FM Stereo and FMX 11 4.2 Multipath 14 4.3 Review of Effects Due to Multipath 16 4.4 Review of Factors Affecting Multipath 17 4.5 Multipath and FMX 19 4.6 Over the Air Experiments 26 4.7 Analysis of Data 37 5.0 Summary 44 6.0 References 45 i1 Acknowledgements The authors wish to acknowledge the following people who have contributed to this study through either discussions, experimental work, or preparation of the final doc- ument.

  • Audio Engineering & Production
    Audio Engineering & Production FMX Broadcasting without overmodulation," Orban explains. The Optimod FMX generator is a standalonestereo generator with an FMX compressor that is designed to plug directly into Orban's FM processing and is opti- mized for the Optimod-FM 8100 and older 8000 models. But Orban says it can also be interfaced to other manufacturers' processing as long as there's an effective low- pass filter and peak limiting. Orban is continuing to test the system to see how it works in the presence of processing and to de- termine any multipath problems that might exist. A product will be available late this year or early Figure 4: "A" is the normal stereo subcarrier, "B" is the same L- R information next year, with pricing in the with the 20 dB FMX gain and flattop compression characteristic.

Tascam's Studio 8 puts all the power of a professional recording facility into an 8-track production system that's as easy to handle as your own instrument. Forget bewildering patch bay jungles. The fully assign- able 8 buss mixer sends your signals anywhere you want them with the flick of a switch. Forget open reel headaches. The unique Load feature loads the tape, senses the end automatically and never lets it run off the reel. And because Studio 8 uses 1/4" tape, you'll never be stuck trying to find someone's rare proorietary tape format. Forget video hassles. The "One Plug" SMPTE/EBU interface gives you easy synchronizer or editor connections. But there's something more. Something that's greater than the sum of the features. Startling sound.
