Analogue FM receivers employ an LC tuning system that generates ‘hiss’
noise at the output, which remains unclipped during off-station tuning.
However, when the received signal level is adequate (i.e., when the receiver
frequency is very close to an FM transmitting station frequency), the limiter
circuit preceding the ratio detector circuit in an analogue FM receiver will
clip/limit any noise riding the FM carrier.
Abstract:
The simple noise muting FM receiver circuit described here eliminates this
‘hissing’ noise from the output of an analogue FM receiver circuit when it is
not resonating to any FM transmitting station’s frequency. In other words,
this circuit mutes the output from an analogue FM receiver when its tuner
circuit is sweeping in between FM stations.
