12. What do we call a circuit that takes several inputs and their respective values to select one specific output line? Name one important application for these devices.
A circuit that takes several inputs and their respective values to select one specific output line is called MULTIPLEXER.
The multiplexer, shortened to “MUX” or “MPX”, is a combinational logic circuit designed to switch one of several input lines through to a single common output line by the application of a control signal.
Applications of Multiplexer:
Multiplexer allow the process of transmitting different type of data such as audio, video at the same time using a single transmission line. Telephone Network – In telephone network, multiple audio signals are integrated on a single line for transmission with the help of multiplexers.
