Homework Help: Boolean logic priority encoder

  1. Apr 8, 2013 #1
    Hello, I need to design a circuit (3-bit priority encoder) whereby:

    - if input X =1, then outputs B1=1, B0=1
    - if inputs X=0, Y=1, then outputs B1=1, B0=0
    - if inputs X=0, Y=0, Z=1 then outputs B1=0, B2=1
    - if all 3 inputs = 0, then outputs B1=0, B0=0

    Would this be the correct way to draw the circuit for this operation ?

    Thanks kindly for any help.

    I suppose you mean B0 = 1.

    Can't you just check it by following the inputs through your circuit?
