A communication channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking. A channel is used for information transfer of, for example a digital bit stream, from one or several senders to one or several receivers. A channel has a certain capacity for trans…

- The following information was deleted from this article (see diff): 1. Channel capacity, shown often as "C" in communication formulas, is the amount of discrete information bits that a defined area or segment in a communications medium can hold. Thus, a telephone wire may be considered a channel in this sense. Breaking up the frequency bandwidth in...
