Logic Gates - Technical MCQs

Q1:

How many inputs of a four-input AND gate must be HIGH in order for the output of the logic gate to go HIGH?

A any one of the inputs

B any two of the inputs

C any three of the inputs

D all four inputs

ANS:D - all four inputs

Yes D is right option. If any of the input is low then output goes low so it is necessary that all input (four input) must be high.
