With a block diagram explain elements of communication system.
Transmitter : A collection of electronic components and circuits designed to convert the information into a signal suitable for transmission over a given communication medium.
Receiver : Another collection of electronic components and circuits that accept the transmitted message from the channel and convert it back into a form understandable by humans.
Noise : Any random, unwanted energy that enters the communications system via the communications medium and interferes with the transmitted signal.
Channel : It provides means of transporting signals from a transmitter to a receiver.
