Abstract :
The reception of frequency modulated signals by means of various adjustments of a tuned circuit is discussed nonmathematically. The simplest method consists in analyzing the signal into a carrier and side bands, and calculating the response of the tuned circuit to each component. The maximum power response is found to be 0.09 of the response with an amplitude modulated transmitter of the same power. There is an inherent discrimination in the receiver against the lower modulation frequencies which just balances a similar discrimination in the transmitter against the higher modulation frequencies.
