A combination of logic gates is as shown in the figure. P, Q, R and S are the inputs and X, Y and Z are outputs. When inputs P and R are "low" and Q and S are "high", the outputs X, Y and Z respectively are

Step-by-step solution

From the given logic circuit, the Boolean expressions for the outputs are: X = P Q Y = R S Z = X + Y Given the inputs: P = 0 (low), Q = 1 (high), R = 0 (low), and S = 1 (high). Substituting these values: X = 0 1 = 0 0 = 0 Y = 0 1 = 0 = 1 Z = 0 + 1 = 1 Thus, the outputs X, Y , and Z are 0, 1 , and 1 respectively. Answer: 0, 1, 1
