Discuss your observations in the report.

1. 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.
