Step 1 of 2 4.035E A 2-input XOR gate gives the output 1 if one of its input is 1. Thus the truth table for the XOR gate is given by as follows. Let X &Y are the inputs and Z is the output of the XOR gate. X Y Z 000 011 101 110 Table 1: Truth table for XOR gate Step 2 of 2 From the truth table, the sum of product expression is given by, The AND-OR circuit of XOR gate is shown in Figure 1: X Y X Y' 2 2 1 XY 3 2 2 Z 3 1 3 2 XY' Figure 1: AND-OR circuit for XOR gate
