The Multiplexer acts as a multiple-input and single-output switch. Multiple signals share one device or transmission conductor such as a copper wire or fiber optic cable.In telecommunications, the analog or digital signals transmitted on several communication channels by a multiplex method. These signals are single-output higher-speed signals. A 4-to-1 multiplexer contains four input signals and 2-to-1 multiplexer has two input signals and one output signal.
