A switching circuit has two control inputs (C1 and C2), two data inputs (X1 and X2), and one output (Z).The circuit performs logic operations on the two data inputs, as shown in this table: C C 00 01 10 11 FUNCTION X1. X2 X1 + X2 X1 X2 X1 X2 (a) Derive a truth table for Z. (b) Use a Karnaugh map to find a minimum OR-AND gate (POS) circuit to realize Z. Activate Windows
