Answer 2

Answer:

The Boolean expression X= (A+B) . (C+D) represents an OR GATE.

Explanation:

On applying the inputs and drawing the schematic diagram of the Boolean expression we get the following conclusion inputs A and B give output X(let’s assume) which is the input to the AND gate and similarly inputs C and D give output Y (let’s assume) which is the 2nd input to the AND Gate. On summarizing the truth table of the final output of the Boolean expression the final results tally the results of the truth table of OR Gate.

OR GATE: -

The truth table governs how the OR gate, a digital logic gate that conducts logical dis junction, functions. If either one or both of the gate's inputs are HIGH, the output will be HIGH. A LOW output is a result if none of the inputs is high.

AND GATE: -

The AND gate implements logical conjunction from mathematical logic; it is a fundamental digital logic gate that functions in accordance with the truth table above. Only when all of the inputs to the AND gate are HIGH does a HIGH output result. If some of the inputs to the AND gate are not HIGH, the output will be LOW.
