AIM:
To design and verify the truth table of a three bit binary to gray code converter.
THEORY:
Code converter is a circuit that makes two systems compatible even though each uses different binary codes. There is a wide variety of binary codes used in digital systems. Some of these codes are Binary Coded Decimal, Gray code, Excess- 3 code , ASCII code, etc.
A combinational circuit performs the transformation of a three bit binary to gray code converter by means of logic gates. The input variables are binary bits named as A,B,C with A as the MSB and C as the LSB. The Gray code output bits are termed as X,Y,Z
with X as the MSB and Z as the LSB.
The Gray code is also called as reflective code. The gray coded number corresponding to the decimal number 2n – 1, for any n, differs from gray coded 0 (0000) in one bit position only.
PROCEDURE:
1. Connections are given as per the circuit diagrams.
2. For all the ICs 7th pin is grounded and 14th pin is given +5 V supply.
3. Apply the inputs and verify the truth table for the three bit binary to gray code converter.
RESULT:
The design of the three bit Binary to Gray code converter circuit was done and its truth table was verified.
