Two Input NOR Gate
Category: Logic Gates
Designer: RANA MUHAMMAD ADNAN KHALIL
Notes
This circuit is designed and simulated in Proteus 7.10. In this circuit you will learn how to make NOR gate practically. 1. This is a two input NOR gate circuit. 2. Before understanding this circuit, first see previous circuits "Two Input OR Gate" and "Single Input NOT Gate" in logic Gates category. 3. NOR gate is the serial combination of two input OR gate and single input NOT gate. 4. The truth table of NOR gate is: In 1: In 2 : Out 0 : 0 : 1 0 : 1 : 0 1 : 0 : 0 1 : 1 : 0 5. From the above truth table we can see that if any input of NOR gate is logic one (1) then output is logic zero (0). 6. The output is logic one (1) only when all inputs are logic one (1). 7. Here logic one (1) means 5V and logic zero (0) means 0V or ground. Application: 1. This circuit is used to understand the working of NOR gate. 2. This circuit is used when you don't have NOR gate IC and you need NOR gate. Download these files for performing more experiments.
