    Half Adder

    The Half Adder is a basic combinational circuit that adds two 1-bit binary numbers and produces a sum and a carry output.

  • 4.2

    Full Adder

    A Full Adder is a digital circuit that computes the sum of three binary bits, providing both a sum and a carry output.

  • 4.3

    Half And Full Subtractor

    This section explains the operation of half and full subtractors, which are combinational circuits used for binary subtraction.

  • 4.4

    Multiplexers (Mux)

    Multiplexers are electronic devices that select one input from multiple sources based on control lines.

  • 4.5

    Demultiplexers (Demux)

    Demultiplexers route one input signal to a specific output line based on control signals.
