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!
