The purpose of a receiver is to select a desired group of frequencies from one transmitter, get rid of all unwanted signals and noise, and then demodulate the signal to obtain the modulating infomation. The better the receiver does its job, the closer the demodulated sigmal will resemble the original signal from the transmitter. Regardless of the type of demodula
