Code convrters

Code converters:

There is a binary of codes used in digital system.

Let us see the procedure to desigh code converters:

STEP 1 : Write the truth table showing the relationship between input code and output code.

STEP 2 : For each output code bit determind the simplest boolien expression using K-map.

STEP 3 : Realize the code converters using logic gates.

 

Design a 4-bit binary to BCD converters ?

Design a logic circuit to convert the BCD to Excess 3 code ?

Design a logic circuit to convert BCD to gray code ?
