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