In our previous tutorials we learnt about Logic buffer and logic inverter. Now we have a tutorial on Logic OR gate. OR Gate The circuit design of OR gate (by using diodes) is given below. The circuit uses two diodes at input side. In all logic circuits, +5 volts is represented as HIGH level logic and 0 volts or ground is represented as the LOW level logic. The two logic levels are represented as binary numbers 0 and 1....
