Concept explainers

Frequency Modulation
Frequency modulation is a method or process of encoding the data of a specific signal (analog or digital) by modulating the carrier wave frequency according to the frequency of the modulated signal. Modulated signals are nothing more than information or …
Question

An FM transmission has a frequency deviation of 20 kHz.

(1) Determine the per cent modulation of this signal if it is broadcasted in the 88-108 MHz

band.

(2) Calculate the per cent modulation if this signal is broadcasted as the audio portion of

a television broadcast.
