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.
How HD Radio Works. The radio waves that carry analog AM and FM signals are limited in the amount of information they can convey, both because of the nature of the waves themselves and the spacing of stations on the frequency band. FM stations are separated by 200 kHz, while AM stations have just 10 kHz between them. Alternate channel spacing of FM stations gives them 400 kHz to work with. The signals broadcast by radio stations are actually spread out on either side of the frequency into Upper and Lower Sidebands (USB and LSB).
