HALF-ADDER:

S = XY' + X'Y , C = XY (These are the outputs)

1. From the equation given for half-adder, develop an equation for which the half-adder can be constructed just with NAND gates. Draw the circuit as per the equation obtained.

2. Explain with reasons and necessary boolean equations why it is easy to construct adder circuits with XOR gates.
