AM & FM Radio Broadcasts.

What is FM Radio?

FM refers to frequency modulation, FM technology in which information (sound) is encoded by varying the frequency of the wave

and the amplitude is kept constant.

FM uses changes in the wave’s

frequency to convey

information.

What is AM Radio?

AM refers to amplitude modulation, AM works by modulating (varying) the amplitude of the signal or carrier transmitted according to the

information being sent, while the frequency remains constant.Modulation is the process of impressing a low frequency information

signal (baseband signal) onto a higher frequency carrier signal.

AM Vs. FMSo, AM (or Amplitude Modulation) and FM (or Frequency Modulation) are

ways of broadcasting radio signals. Both transmit the information in the form of electromagnetic waves.
