The symbol for NAND is the same as that for AND except for the addition of a small circle on the right side. The name NAND comes from joining NOT and AND. Its output is 0 when the two inputs are 1, and for all other cases, its output is 1. You can think of it as an AND gate followed immediately by a NOT gate. The NAND gate behaves in the opposite fashion to an AND gate. The output is 1 if both inputs are 1, and for all other cases the output is 0. The AND gate has two inputs and one output. Tables listing all logical possibilities like this are known as truth tables. The two possibilities are written out in the table below. The NOT gate is also known as an inverter because the output is the exact opposite of the input. Additionally, you can rename an output by double clicking on its label. If you need more space, click on the 'Full screen mode' button which will increase the size of the workspace to fill the size of the window. Input (solid circle) and drag away and release, or alternatively you can right click anywhere on the connection. To remove connections, you can click on the To delete nodes, click the small cross in the top right corner of its enclosing box.

You can drag it to your desired position. The new node will be placed in the top left hand corner, and To add a new logic gate, or an additional input or output block, choose from the dropdown menu and then click 'add node'. This is our way of differentiating between 0 (off) and 1 (on). Click the on/off switch and see what happens. Our 'on/off' switch and 'output block' aren't actually logic gates,īut they are required because they give us the 1s and 0s needed to see how the gates behave. On/off switch, and release the mouse when you are over the solid circle on the left side of the 'output' block.įor each of the logic gates, outputs are hollow circles, and inputs are solid circles. To connect them, click and drag from the hollow circle on the right side of the You are presented with a simple on/off input and an output.

Switches are connected in parallel in OR Gate using switch, same as it if we connect transistor in parallel, so that any one of the buttons get closed, LED will glows. We need 2 inputs and 1 output device that are buttons and led respectively. OR gate using transistor works similar to OR gate using switch. AND Gate Using NPN Transistor OR GATE USING TRANSISTOR

Switches are connected in series in AND Gate using switch, same as we connected the transistor in series, so that until both buttons are not closed, the LED will not glows. NOT Gate Using NPN Transistor AND GATE USING TRANSISTORĪND gate using transistor works similar as AND gate using switch. When we press the button it activates it’s base and maximum current passes through emitter rather than collector. So the only path remaining for current to reach to the ground is collector i.e. Initially when the button is open circuited, Transistor wouldn’t allow the signal to pass through the emitter. We need 1 input device and 1 output device that are button and led respectively. NOT gate using transistor works similar as NOT gate using switch. Here we are using the transistor as a switch and controlling the base signal using a button so that we can control and see logic given to base. One more interesting thing is IC’s are made of logic circuits and logic circuits are made up of logic gates, So basically IC’s have capacitors, resistor & transistors on chip for logical circuits, that’s why IC’s understand logic 1 & 0 as logic high and low only.
