PROCEDURE:
1. Circuit connections are given as per the circuit diagram.
2. The +5V DC power supply is properly connected to Vcc and GND pins
(14 & 7) of each IC.
3. Logical input conditions are given as per the Truth Table.
4 .Logical outputs are observed and verified.
RESULT:
Thus the Half Adder and Full Adder circuit is constructed and the output is verified using the Truth Table.
