Types of AM Radio Receivers
A radio receiver is a device which reproduces the modulated or radio waves into sound waves. The radio receivers used in reproducing amplitude modulated signals are called AM radio receivers. So as to reproduce the AM wave into sound waves, every radio receiver must perform the following functions: Related: General Principles of Radio Broadcasting, Transmission…

Demodulation in Telecommunication Systems
Demodulation is the process of recovering the audio signal from the modulated wave. Demodulation is also known as detection in communication systems. Why Demodulation is needed in Telecommunication Systems Amplitude modulated wave consists of carrier and sideband frequencies. The audio signal is contained in the sideband frequencies which are radio frequencies. If the modulated wave…
