To verify De Morganâ€™s first and second theorems.

**VERIFICATION OF DE MORGANâ€™S
THEOREMS**

To
verify De Morganâ€™s first and second theorems.

Power
Supply (0 â€“ 5V), IC 7400, 7408, 7432, 7404, and 7402, Digital IC trainer kit,
connecting wires.

De Morganâ€™s first theorem, De Morganâ€™s second theorem

Â· The connections are made for LHS of the theorem as shown in the circuit diagram using appropriate ICs.

Â·
The output is noted and tabulated for
all combinations of logical inputs of the truth table.

Â· The same procedure is repeated for RHS of the theorem.

Â·
From the truth table, it can be shown
that

Â· The connections are made for LHS of the theorem as shown in the circuit diagram using appropriate ICs.

De-Morganâ€™s first theorem, De-Morganâ€™s second theorem

De
Morganâ€™s first and second theorems are verified.

The
pin diagram for IC 7408, IC 7432 and IC 7404 can be taken from previous
experiment

Precautions

V_{CC}
and ground pins must not be interchanged while making connections. Otherwise
the chip will be damaged.

For
the ICs used, 5V is applied to the pin 14 while the pin 7 is connected to the
ground.
