Question 168 of 209

A logic gate circuit has two inputs AA and BB and output YY. The voltage waveforms of A,BA,B and YY are shown below

The logic gate circuit is

Show answer and solution

Answer: (A) AND gate

Making Truth table of the given wave from,

It is clear from the above table that the output is present when both the inputs are high. Even when any of the input is not present, the output is low. This is the function of the AND gate. Hence, the logic gate present is AND gate.
