PhysicsSingle correct+4 / -1Question 49 of 90

A logic gate circuit has two inputs A and B and output Y. The voltage waveforms of A, B and Y are shown below.

The logic gate circuit is:

Timing diagram: A has three equal pulses; B is high from the start of the first A pulse until the second A pulse begins, and again during the third A pulse; Y is high only where A and B are both high (first and third A pulses).

A

AND gate

B

OR gate

C

NOR gate

D

NAND gate

Answer and worked solution

Official answer: A

Y is high only while both A and B are high: AND gate.

(A)
