In this topic, you study how to design Binary to Gray Code Converter Circuit and draw the logic diagram.
The conversion of 4-bit input Binary code (A B C D) into the Gray code output (W X Y Z) as shown in truth table 1. The 4-bit input so 16 (${2^4}$) combinations are
In this topic, you study how to design Binary to BCD Code Converter Circuit and draw the logic diagram.
The input is a 4-bit binary code (A B C D) so 16 (${2^4}$) combinations are possible. Hence the output should have 8-bit, but first three bits will all be a 0 for all combinations of inputs, the output can be treated as 5-bit BCD code (W X Y Z E). The conversion of binary code into BCD code as shown in
In this topic, you study how to design BCD to Excess-3 Code Converter Circuit and draw the logic diagram.
