About this document

Overview of Communication Systems by riju_rahman is a document available to read on EtoBox.

The exchange of information between a sender and receiver is called communication. Every communication system has three basic elements - a transmitter that converts a message into an electrical signal, a channel to transmit the signal, and a receiver to receive the signal. Modulation involves superimposing a message signal onto a high-frequency carrier wave for long-distance transmission. Common modulation methods are amplitude modulation, frequency modulation, and phase modulation.
