Question

Explain the working of a OR gate. Give the symbol, Boolean expression and truth table of a OR gate.

Answer 1

Working of OR Gate:

In mathematical terms, OR gate works on addition operation and may have two or more inputs but it produces only one output.

An OR gate produces an output of logic 0 or LOW only when all the input values are at logic 0 or at LOW state.

The operational symbol of OR gate is ‘+’ and the expression for OR gate is Z (output) = x+y+ … (Inputs).
