Functional Description:
The output of the OR Gate operator is the logical OR of its inputs,
where y is the output, are the inputs, and n is the number of inputs. In other words, the output state is LOW if all inputs are LOW. If any input is HIGH, the output is HIGH. Below is the truth table for a 3-input OR-gate:
