How to Design a 3-Bit Priority Encoder Circuit?

[fran1942]

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.

- if all 3 inputs = 0, then outputs B1=0, B0=0

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

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