I have been given the boolean expression:

O/P = W.X'.Y.Z + W.X'.Y.Z' + W.X.Y.Z' + W.X.Y.Z + W.X.Y'.Z' + W.X.Y'.Z

I have been asked from this to draw up a truth table to define the outputs and then draw the original circuit.

Can someone please give me a few pointers on how to go about this.

Kind regards
