Multiplexer and demultiplexer demonstration (4 bit)

Description

This applet demonstrates the function of 2-bit and 4-bit multiplexer and demultiplexer components. The internal structure of these components will be shown in the next applet(s). Please play with the select input switches to study the behaviour of the components.

A multiplexer circuit works similar to a standard multi-way switch. It transmits the selected input directly to the single output. A typical use is to select the new input value for a flipflop from a set of several alternatives.

For demonstration purposes, the data inputs of the multiplexers are not all connected to static input values, but also to two clock generators with different clock periods. This should allow you to directly 'see' which input signal is transmitted by the multiplexer.

The demultiplexer performs the inverse function of the multiplexer. It transmits the value on the single data input to the selected one of its several outputs.
