Converter - logic gates

  1. Nov 16, 2013 #1
    1. The problem statement, all variables and given/known data

    I have to build some converters (only for 4 bits) and i didn't understand how. How do i proceed? Which logical gates combined in such a way give me the y3y2y1y0 answer for x3x2x1x0?
    For example, build a coverter from EXCES3 to BCD, or from GRAY TO BCD, or C1 complement to C2 using logical gates (AND,OR,XOR,NAND,etc.)


    2. Relevant equations




    3. The attempt at a solution

    Well, i can make the truth table for x3x2x1x0.



    Thank you!
