4x1 Mux Circuit Diagram. From truth table we can directly write the boolean function for output y as. In 4 1 mux there will be 4 input lines and 1 output line.
This hardware schematic is the rtl design of the circuit. 4 to 1 multiplexer. But you d then have a logic with 4 output pins.
Hence this would be your final design.
And to control which input should be selected out of these 4 we need 2 selection lines. So at the least you have to use 4 4 1 mux to obtain 16 input lines. One of these 4 inputs will be connected to the output based on the combination of inputs present at these two selection lines. A multiplexer or mux is a combinational circuits that selects several analog or digital input signals and forwards the selected input into a single output line.
