May 15, 2024 · Frequency Modulation or FM is a method of encoding information on one carrier wave by changing the wave carrier frequency. Learn more about frequency modulation, its application, advantages, disadvantages and more in this article
Frequency modulation can be classified as narrowband if the change in the carrier frequency is about the same as the signal frequency, or as wideband if the change in the carrier frequency is much higher (modulation index > 1) than the signal frequency.
Frequency modulation is a technique or a process of encoding information on a particular signal (analogue or digital) by varying the carrier wave frequency in accordance with the frequency of the modulating signal.
Definition: A category of angle modulation in which the frequency of the carrier wave is changed according to the amplitude of the message signal is known as frequency modulation. It is abbreviated as FM and is a widely used analog modulation technique.
But we’re looking for frequency modulation, not phase modulation, so we want the excess frequency to be linearly proportional to the baseband signal. We know from the first page of this chapter that we can obtain frequency by taking the derivative, with respect to time, of phase.
Understanding Frequency Modulation (FM), Frequency Shift Keying (FSK), Sunde’s FSK and MSK and some more. The process of modulation consists of mapping the information on to an electromagnetic medium (a carrier). This mapping can be digital or it can be analog. The modulation takes place by varying the three parameters of the sinusoid carrier.
At its core, frequency modulation involves changing the frequency of a carrier signal in accordance with the input signal. The input signal, which carries the message to be transmitted, is used to modulate the frequency of the carrier wave.
