Design 3 bit Binary to Gray code converter. written 2.5 years ago by Vedant Chikhale ♦ 260: modified 19 months ago by Abhishek Tiwari ♦ 1.4k: mypost dsd(33) number system code conversion. ADD COMMENT • FOLLOW • SHARE • REPORT 1 Answer. 2. 23k views. written 2.5 years ago by Vedant Chikhale ♦ 260 For a binary code, each bit has a value that depends on its position in the number.. Similarly, for gray code, its specialty lies in the fact that it requires each subsequent number to differ from its predecessor by only 1 bit.You can notice this when we derive the truth table below Writing truth table showing the relation between Binary as input and Gray code as output. Since input is BCD, only 10 combinations can be made using 4 bits. (0 to 9). For each Gray code output D3, D2, D1 and D0, write Karnaugh-Map. From the K-Map, obtaining a simplified expression for each Gray Code output in terms of BCD inputs 6.8.2 Binary to Gray Code Converter : A Gray code is one in which adjacent numbers differ by one symbol. There are many Gray Codes, even in binary. They can be devised in any base. When Gray (or Gray code) is used without specifying which one, what is meant is reflected Binary Gray Binary Numbers is default way to store numbers, but in many applications binary numbers are difficult to use and a variation of binary numbers is needed. This is where Gray codes are very useful. Gray code has property that two successive numbers differ in only one bit because of this property gray.

A gray to binary code converter can be implemented using XOR gates. For n input, n-1 gates are required. As shown in the image below for 4 inputs, 3 XOR gates are used: Hope you find the information presented here useful. Feel free to leave your footprints in the comments section below for any further queries, feedback or suggestions Binary to Gray Code Converter: This same technique can be applied to make gray to binary converter. There will be 4 input bits, which represent binary and 4 output bits which represent equivalent gray code. Since we are creating binary to gray code converter so, we need to find expressions for each gray code output in terms of input binary bits Gray code do not have place value for its digits. Any successive codes in Gray code system have only one bit changes. Binary to gray code conversion can be made easy with an example: Let us convert a binary value of 1010 to gray code: Step 1: The MSB (Most Significant Bit) of a gray code and binary code will be the same Since the outputs depend only on the present inputs, this 4-bit Binary code to Gray code converter is a combinational circuit.
