### To Implementation of Binary to Gray conversion using Logic gates

**The following electronics components are required.**

__Apparatus required:-__•EX-OR Gate (IC-7486)

•Digital Trainer KIT

•Breadboard

•Connecting wires

__Description:-__The availability of large variety of codes for the same discrete elements of information results in the use of different codes by different systems. A conversion circuit must be inserted between the two systems if each uses different codes for same information. Thus, code converter is a circuit that makes the two systems compatible even though each uses different binary code.

The bit combination assigned to binary code to gray code. Since each code uses four bits to represent a decimal digit. There are four inputs and four outputs. Gray code is a non-weighted code.

The input variable are designated as B3, B2, B1, B0 and the output variables are designated as C3, C2, C1, Co. from the truth table, combinational circuit is designed. The Boolean functions are obtained from K-Map for each output variable.

A code converter is a circuit that makes the two systems compatible even though each uses a different binary code.

Now the OR gate whose output is C+D has been used to implement partially each of three outputs.

__Logic Diagram for Binary to Gray Code Converter:-__**G3=B3**

__K-Map for G3:-__

**K-Map for G2**:-

**K-Map for G1**:-

**K-Map for G0**:-

__Truth-Table:-__

**Procedure to Perform:-**•In the case of binary to gray conversion, the inputs B0, B1, B2 and B3 are given at respective pins and outputs G0, G1, G2, and G3 are taken for all the 16 combinations of the input.

**All the output verified the result of Truth Table.**

__Conclusion: -__

**Precaution in lab:-**•All the connections should be tight and proper.

•Handle the ICs carefully.

•Check the connection once again before Switching on the Digital Trainer KIT.

•Switch of the Trainer Kit after performing the Experiment.
