Theory:
In this experiment I am going to design a half adder logic circuit by using NAND gates
in arrangement. And finally I have to write the truth table for the expression of half
adder circuit.
Apparatus:
Logic trainer
Power supply
Jumper wires
Digital multi meter
Procedure:
Connect the circuit according to the circuit diagram.
Use A and B two inputs for a NAND gate.
Now take a output which is common for next NAND gates.
Connect input A direct with 2nd NAND and as first input and use the output of first
gate as second input for this gate
For third NAND gate connect B input direct with second input and common
output of first gate as first input.
The output of second and third logic gate connect with fourth NAND gate and take
a single output.
The output of first NAND logic gate connect with fifth NAND gate as once and
take a single output
Draw a truth table for sum and carry.
