The selection of a specific output line is controlled by the bit values of n selection lines. Difference between multiplexer and decoder electrical. Understanding how to implement functions using multiplexers. A multiplexer is often written as mux in the abbreviated form.
Specifies whether 2channel audio is encoded as stereo or dual mono. Multiplexer is a combinational logic circuit which allows only one input at a particular time to generate the output. It has multiple inputs and outputs, and its usually used to convert coded inputs into coded outputs provided both of them are different from each other. The output goes to an indexselectable demultiplexer, whose behavior is controlled by a second dc input entry to feed two outputs. Each of these multiplexers will receive one bit of the digits total of four bits, one per multiplexer from the registers in order by the significance of the digits stored in the registers green box.
