ABSTRACT
The tuning of a frequency modulated (FM) receiver to a FM radio station frequency involves a lot of ‘hissing’ noise in between the stations, which is very irritating for the operator and as such undesirable. Digital FM receivers are free from this problem, because in them the output is automatically clipped during off-station gaps. However, digital FM receivers are comparatively much costlier than their analogue counterparts.
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.
This work is on 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.
