    A 4:1 multiplexer is a logic circuit that selects one of four input lines to pass to the output based on the values of two select lines. It uses logic gates to implement the functionality of transmitting multiple signals over a single line. The truth table and observation table demonstrate how the multiplexer selects the correct input line to output based on the binary values of the select lines.

    TITLE :- Implementation of 4:1 multiplexer circuits using logic gates.

    Object :- To construct 4:1 multiplexer circuit using logic gates & to show its
    operation.

    List of equipments :-

    Name Manufacturer Specification


    Power supply
    Logic probe

    Theory :-

    Multiplexing is the process of transmitting a large number of information


    over a single line. A multiplexer is a combinational logic circuit which has 2n
    input line, n select and only one output line. The selection of a particular
    input line is controlled by the set of select line. It determines which inputs
    will go to the output.
