He is saying the same thing I was. You will study it, and soon. Basically it is a way of picking gates from within a truth table.I suggest making a Karnaugh map and simplifying it. It is a more algorithmic and visual approach.
There is not much you can do after that. All I see is:x'y'z' + wx'z' + wx'y + w'x'z
I'm not sure what to do after i factor x' out... or even if thats the right thing to do in the first place
x'(y'z' + wz' + wy + w'z)
It is enough to make using gates though.There is not much you can do after that. All I see is:
x'(y'z'+z'w(y+y')+yw+zw')=
x'(y'z'+yz'w+y'z'w+yw+zw')=
x'(y'z'(1+w)+yw(1+z')+zw')=
x'(y'z'+yw+zw').
As I said, without a Karnaugh map, this doesn't make much sense.
The original expression is in a standard form called "sum of products". Each of the product terms has three of four boolean variables. In order to "simplify" the expression you need to reduce either the number of terms or the number of variables in some terms. If you write out a truth table you should be able to spot a pattern that will suggest simplification if it is possible. Otherwise, transforming the expression may not count as a "simplification".x'y'z' + wx'z' + wx'y + w'x'z
