Question

What does FM stand for?

Answer 1

Hint: The step of modulation in a communication system is crucial.Modulation is defined as a procedure in which a feature of a high frequency signal wave (carrier wave) is changed in response to the instantaneous value intensity of a low frequency signal wave (modulating wave.)

Complete answer:
FM is the abbreviation for frequency modulation. Frequency modulation is a method of encoding information on a signal (analogue or digital) by shifting the carrier wave frequency in line with the modulating signal's frequency. A modulating signal is simply information or a message that must be conveyed after being turned into an electronic signal, as we all know.

Additional information: Frequency modulation works in a similar way to amplitude modulation in that the input signal modulates a carrier signal. In the case of FM, however, the modulated signal's amplitude is maintained or remains constant.

When it comes to frequency modulation applications, radio transmission is the most common. It has a higher signal-to-noise ratio, which gives it a significant advantage in radio transmission. As a result, there is little radio frequency interference. This is one of the primary reasons why many radio stations use FM to transmit music.

Note: The two main methods of angle modulation are frequency modulation and phase modulation; phase modulation is frequently employed as a step between frequency modulation and frequency modulation. In contrast to amplitude modulation, which changes the carrier wave's amplitude while keeping the frequency and phase constant, these methods change the carrier wave's amplitude while keeping the frequency and phase constant.
