As shown in Figure a, it is used in positive logic systems and is called a positive OR gate. As shown in Figure b, it is used in negative logic systems and is called a negative OR gate. The OR gate circuit that omits the gate resistor is shown in Figure c. d The picture shows the "OR gate" logic symbol. Latest Basic Circuits Circuits
