Communication Channel: Atmosphere

Science > Physics > Communication > Communication Channel: Atmosphere A communication channel is a link connecting a transmitter and a receiver. It is the physical medium which carries the signal from the transmitter to the receiver ideally without any noise or distortion. The atmosphere, optical fibres, parallel wires, coaxial cables, etc. are used as communication […]
