Question 166 of 209

For the given logic gates combination, the correct truth table will be

AA B X 0 0 1 0 1 0 1 0 0 1 1 0BA B X 0 0 0 0 1 1 1 0 1 1 1 0CA B X 0 0 1 0 1 0 1 0 1 1 1 0DA B X 0 0 0 0 1 1 1 0 1 1 1 1

Show answer and solution▾

Answer: (B) A B X 0 0 0 0 1 1 1 0 1 1 1 0

A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If not all inputs to the AND gate are HIGH, LOW output results.
But in case of OR Gate, for the output to be 1, at least input one OR two must be 1.
NOR Gate reverses the logic state.
Therefore, for all possible combination of inputs, outputs at different stages will look like as given below.
