What are some factors that can affect the modulating signal frequency of an FM receiver?

Several factors can affect the modulating signal frequency of an FM receiver:

Transmitter Characteristics: The frequency of the carrier wave generated by the FM transmitter is a key factor influencing the modulating signal frequency. Any variations in the carrier frequency will directly impact the modulating signal frequency.

Propagation Conditions: The propagation of radio waves through the atmosphere and other mediums can introduce frequency shifts due to phenomena like multipath propagation, Doppler effects, and atmospheric disturbances. These frequency shifts can affect the modulating signal frequency at the receiver.
