Verilog Multiplexer. A multiplexer is a device that selects one output from multiple inputs. It is also known as a data selector. We refer to a multiplexer with the terms MUX and MPX. Multiplexers are used in communication systems to increase the amount of data sent over a network within a certain amount of time and bandwidth. Basically to implement a full adder,two 4:1 mux is needed. Let's start from the beginning. To implement full adder,first it is required to know the expression for sum and carry.
