1. Consider the following logic circuit diagram: P Q R S a. What is the output S when P = 1, Q = 0, and R = 1? b. What is the output S when P = 0, Q = 0, and R = 0? c. What is the output S when P = 1, Q = 1, and R = 1? d. Write a Boolean expression for the output S in terms of the inputs P, Q and R. e. Write an input-output table for this circuit diagram. 1.
