This device combines multiple circuits at one end of a connection into a single complex circuit on a single wire. The signal is then split into the individual connections on the other end.

Multiplexer

Explanation:

-In electronics, a multiplexer, also known as a data, is a device that selects between several analog or digital input signals and forwards it to a single output line.

-This device combines multiple circuits at one end of a connection into a single complex circuit on a single wire.

-The selected signals is then transmitted at a higher speed.
