To verify De Morgan’s first and second theorems.

**VERIFICATION OF DE MORGAN’S
THEOREMS**

To
verify De Morgan’s first and second theorems.

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

De Morgan’s first theorem, De Morgan’s second theorem

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

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

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

·
From the truth table, it can be shown
that

De-Morgan’s first theorem, De-Morgan’s second theorem

De
Morgan’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.
