3 Figure 1. Basic principles of FM transmission and reception Introduction: The art and science of wireless microphone design have progressed in recent years to a point where reliable and flexibleperformance can be taken for granted in even the most complex venues. What remains is for this level of ...

4 FM has been used for broadcast transmission of high quality audio since the mid-1950s, and its primary advantages are wideaudio bandwidth and relative freedom from external electrical disturbances as compared to AM (amplitude modulation).The chief factors that determine the ultimate performance ch...

5 Noise Considerations: Monophonic FM broadcast transmission normally has a very high signal-to-noise ratio because of relatively high signal strength and high modulation index. In the wireless microphone area, where we are “crowding”many channels into a relatively small radiated bandwidth, the usab...
