Going further with the details on FM radio broadcast, we come up with the point that for accommodating an audio signal in FM radio, it does not require a bandwidth of 200 kHz. What is all required is 20 kHz to 30 kHz for a narrowband FM radio broadcast or FM signal. The 200 kHz bandwidth enabled space for Â±75 kHz signal deviation from the appointed frequency. Moreover, guard bands for minimizing or eliminating adjacent channel interference.
For example [2], in North America, the maximum frequency deviation, â f, is 75 kHz for commercial FM broadcasting. If the maximum message frequency is equal to 15 kHz for audio, then Î²= kHz kHz =75 15 5, and the FM bandwidth is BW FM = + 2(5 1)15 kHz =180 kHz.This is close to the allotted 200 kHz channel bandwidth.he FCC has set modulation limits of 100% modulation (an instantaneous frequency deviation of 75 kHz corresponds to a 100 percent modulation) for stereophonic transmission and up to 110. percent modulation for SCA multiplex subcarriers under certain conditions [5].
