One positive pulse with tw = 75 µs is applied to one of the inputs of an exclusive-OR circuit. A second positive pulse with tw = 15 µs is applied to the other input beginning 20 µs after the leading edge of the first pulse. Which statement describes the output’s relation with the inputs?
A. The exclusive-OR output is a 20 s pulse followed by a 40 s pulse, with a separation of 15 s between the pulses
B. The exclusive-OR output is a 20 s pulse followed by a 15 s pulse, with a separation of 40 s between the pulses
C. The exclusive-OR output is a 15 s pulse followed by a 40 s pulse
D. The exclusive-OR output is a 20 s pulse followed by a 15 s pulse, followed by a 40 s pulse
Answer:D
