Multiplexer & Demultiplexer

Multiplexers and demultiplexers are electronic circuits that are used to transmit and receive multiple signals over a single channel. They are essential components of digital systems and are used to reduce the number of transmission lines required to transmit multiple signals.

A multiplexer, also known as a mux, is a digital circuit that can select one of several input signals and transmit it to a single output line based on a control signal. A multiplexer can have two or more inputs and a single output, and the selection of the input is determined by the binary value of the control signal. Multiplexers are used to reduce the number of transmission lines required to transmit multiple signals over a long distance.

A demultiplexer, also known as a demux, is a digital circuit that can distribute a single input signal to one of several output lines based on a control signal. A demultiplexer can have a single input and two or more outputs, and the selection of the output is determined by the binary value of the control signal. Demultiplexers are used to receive multiple signals transmitted over a single line.

Multiplexers and demultiplexers are commonly used together in digital systems to transmit and receive multiple signals over a single channel. They are used in various applications, including digital signal processing, telecommunications, and data storage systems. Multiplexers and demultiplexers are also used in memory systems to store and retrieve data from memory cells.

Multiplexers and demultiplexers can be designed using various technologies, including transistor-transistor logic (TTL), complementary metal-oxide-semiconductor (CMOS), and field-programmable gate arrays (FPGAs). They can also be cascaded together to increase the number of inputs or outputs.
