To Implementation of Gray to Binary conversion using Logic gates.

Written by @
Apparatus required:-The following electronics components are 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 Gray to Binary Code Converter:-

K-Map for B3:-                                   
K-Map for B2:-
K-Map for B1:-
K-Map for B0:-
Truth-Table:-

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

    plotins are wrong for b2 and b1

  9. totally wrong. are you out of your mind you are plotting the k-map of b3,b2,b1,b0 on the basis of g3,g2,g1,g0 which is wrong.
