Why does an FM receiver not need an AGC feedback path?

An FM receiver does not need an Automatic Gain Control (AGC) feedback path because frequency modulation is less affected by amplitude variations in the received signal. FM demodulation primarily relies on changes in frequency rather than amplitude, allowing the receiver to maintain consistent audio quality regardless of signal strength. Consequently, the need for AGC to manage varying signal amplitudes is minimal, as the demodulated audio remains relatively unaffected by these fluctuations.
