Electronics and Communication

In this activity you will be able to (i) Construct , manipulate and simulate the logic circuits. (ii) verify the truth tables of AND, OR, NOT, EX-OR, NAND and NOR gates STEPS: • Open the browser and type “circuitverse.org/simulator” in the address bar. • Click ‘Gates’ tab from the circuit elements. Select the gate you want to verify and drag it in to the stage.

• Nodes in the logic gates are connected through wires. Wires can be drawn by dragging from the nodes with the help of mouse. • Select ‘input tool’ from input tab. Drag and keep it as two inputs.

• Select ‘output tool’ or ‘digital LED’ from output tab. Drag and keep it as output. • Verify the truth tables of AND, OR, NOT, EX-OR, NAND and NOR gates. You can verify De Morgan’s first and second theorems.
