Logic Realization:

PROCEDURE:

·        Check all the components for their working.

·        Insert the appropriate IC into the IC base.

·        Make connections as shown in the circuit diagram.

·        Verify the Truth Table and observe the outputs.

RESULT: Binary to gray code conversion and vice versa is realized using EX-OR gates and NAND gates.
