1:4 MUX in VHDL
4:1Multiplexer: Multiplexer is a combinational circuit which selects one of the input and passes it the output depending upon the input given to the selection line. It has one output n selection line and 2 n input line . It is a multiplexer I0,I1, I2, I3 are the four inputs .s0 and s1 are the selection lines. There is a single output y which selects either of the four inputs. : Truth table for4:1 multiplexer
