Adder and Mulplexer task

Using the logic gates, build a half adder. Verify and record the operation of the circuit for
all possible input combinations.
2. Using the logic gates, build a full adder. Verify and record the operation of the circuit for
all possible input combinations. Derive the equations for the sum and carry out.
3. Using the logic gates, build a 4-input multiplexer. Apply a 1 kHz square wave to input
Do, with D, and D3 connected to ground and D2 connected to Vec- Connect the output X
to an oscilloscope. Change the selector switch inputs and observe the output waveform.
Discuss your observations in the report.
