I have this circuit :
I'm trying to write down the logic of every output (W,X,Y,Z), to get a truth table out of it :
W = NOT (A OR B) X = NOT A AND B Y = A AND NOT B Z = A AND B
But when compares to the source, my truth table is wrong, so I know that my logics are all wrong.
I always start from the right to left everytime I want to understand a logic circuit, for example, in this case, output W is the output of an AND gate between two NOT parameters
W = NOT X AND NOT Y, but where do "X" and "Y" in this case come from, obviously not A and B? Look at the logic circuit, I felt like I was lost in a maze! Any suggestions, or hints to help me to understand this kind of logic circuits easier is greatly appreciated!
