Learning Objective |
In this tutorial, we will learn about

| Slide 3:
Prerequisite |
To follow this tutorial, you should have a basic knowledge of,

To record this tutorial, I am using:
|
| Slide 5:
NOR Gate |
|
| NOR Gate.png | It is the combination of two basic logic gates, the OR gate and the NOT gate connected in series.
We will make this circuit for the NOR Gate demonstration. |
| Show the diagram | To do this experiment, we will need
|
| Let us open the CircuitJS interface
Click on File in the menu bar and select New Blank Circuit. | |
| Click on the Draw option Browse through the menu
Select OR Gate |
Click on the Draw menu and select Logic Gates, Input and Output.
Then select Add OR Gate. Drag and draw the OR gate in the working area. |
| Cursor on the interface. | We need two inputs and one output to see the result of the NOR Gate. |
| Select Logic Input | Go to the Draw menu and select the Logic Gates, Input and Output.
Select Add Logic Input and draw the logic input as shown. Right click on the logic input and select the Edit option. In the pop-up window, check the Numeric box and click on the OK button to save the changes. By doing this, the input values will be shown in either 0’s or 1’s. |
| Right click on the logic input component >> select the Duplicate option. | We need two logic inputs to build the NOR gate.
Right click on the logic input component and select the Duplicate option. Connect both the logic input to the OR Gate as shown. |
| Select Add Inverter | We require a NOT gate to get the desired output of NOR Gate.
Click on Draw and go to Logic Gates, Input and Output and select Add Inverter option. The NOT gate is named as Inverter in CircuitJS. Drag and draw the NOT gate in the working area. Connect the output of the OR gate to the input of the NOT gate. |
| Select Logic output | Now we need a logic output to see the result.
Click on Draw and go to Logic Gates, Input and Output. Select Add Logic output component from the list. Drag and draw the Logic output component. Right click on the Logic output component and select Edit option. In the pop-up window, check the Numeric box and click on the OK button to save the changes. By doing this, the output values will be shown in either 0’s or 1’s. Connect the logic output to the output pin of NOT gate. |
| Use Add text option to give labels | Use the Add text option to give names to the inputs and output pins.
Let us label the inputs as A and B, and output as Y. |
| NOR Gate Truthtable.png | This is the truth table for the NOR Gate, where A and B are the inputs and Y is the output.
The NOR gate output is 1, only when both the inputs are 0. |
| Let us go to the CircuitJS simulator to verify the truth table of the NOR gate. | |
| Working of the circuit | For the first condition in the truth table, both inputs A and B are 0, that is, they are LOW.
By default, the values of both the inputs is 0. Notice that the output Y in the circuit is showing value 1, that is, the output Y is HIGH. Thus the first condition is verified. |
| To verify the second condition in the truth table, we need to change the value of input B.
To change the value of the input from 0 to 1 or vice-versa, click on the input value. Click on the input B value, and notice the input value changes from 0 to 1. The result at the output Y changes, that is, the output Y shows 0 value. The second condition from the truth table is verified. Check the remaining two input conditions for the NOR gate with the truth table. | |
| Symbol_NOR Gate.png | NOR gate is represented with this symbol.
Note the small circle added in the OR gate which represents the NOR gate. |
| In CircuitJS, a NOR gate component is available.
Let us see how to use it. Go to Draw, then select Logic Gates, Input and Output, and select the Add NOR gate option. Drag and draw the gate in the work area. | |
