Soon after source encoding, the digitized sign is processed in the channel encoder, which introduces redundant facts which allows faults to be detected and corrected. The encoded signal is created appropriate for transmission by modulation onto a carrier wave and should be produced part of a larger signal in a very process often known as multiplexing. The multiplexed signal is then sent right into a numerous-entry transmission channel. Following transmission, the above method is reversed on the obtaining close, and the data is extracted.
