<strong>Design</strong> <strong>Of</strong> <strong>Digital</strong> <strong>Circuits</strong> Lab Manual<br />

EXPERIMENT -4<br />

1 AIM: Implement half adder and full adder circuits<br />

2 TOOLS/APPARATUS: IC 7486, IC 7432, IC 7408, IC 7400, Power supply, Connecting wires,<br />

Multimeter etc.<br />

3 STANDARD PROCEDURES:<br />

3.1 Analyzing the Problem:<br />

To implement half and full adder we require X-OR gates, AND gates, OR Gate. Pin Diagrams of<br />

these gates are as below.<br />

<br />

Derive the Equation for Sum and Carry.<br />

Pin Diagrams of Basic gates ICs used in experiment:<br />

XOR Gate(IC 7486) AND Gate(IC 7408) OR Gate(IC 7432)<br />

Truth Tables of Basic gates used in experiment:<br />
