Experiment Name

Design, Construction, and Verification of Basic Logic Gates (AND, OR, and NOT) Using AutoCAD

Theory

1. NOT Gate (Inverter):

   • The NOT gate produces the complement of its input signal.
   • It has one input and one output.
   • When the input is high (1), the output is low (0), and vice versa.
   • The truth table for a NOT gate:
     Table

     Input (A)	Output (Y)
     0	1
     1	0

2. AND Gate:

   • The AND gate produces a high output only when both inputs are high.
   • It has two inputs and one output.
   • The truth table for an AND gate:
     Table

     Input A	Input B	Output Y
     0	0	0
     0	1	0
     1	0	0
     1	1	1

3. OR Gate:

   • The OR gate produces a high output if any input is high.
   • It also has two inputs and one output.
   • The truth table for an OR gate:
     Table

     Input A	Input B	Output Y
     0	0	0
     0	1	1
     1	0	1
     1	1	1

Apparatus

1. AutoCAD software
2. Computer with appropriate system requirements
3. Circuit components (resistors, wires, etc.)

Procedure

1. NOT Gate (Inverter):

   • Create a schematic diagram for the NOT gate using AutoCAD.
   • Label the input and output terminals.
   • Simulate the circuit to verify its functionality.

2. AND Gate:

   • Design a schematic for the AND gate using AutoCAD.
   • Ensure proper connections and labeling.
   • Simulate the circuit to confirm its operation.

3. OR Gate:

   • Create a schematic combining the OR gate components using AutoCAD.
   • Arrange the components appropriately.
   • Simulate the circuit to validate its behavior.

4. NOR Gate (Optional):

   • Design a schematic for the NOR gate using AutoCAD.
   • Verify the truth table for the NOR gate.

Objective

The objective of this experiment is to design, construct, and verify basic logic gates (NOT, AND, and OR) using AutoCAD. By simulating the circuits, we aim to understand their behavior and ensure correctness.

Conclusion

In this lab, we successfully designed, constructed, and verified basic logic gates using AutoCAD. We observed the expected behavior of each gate based on their truth tables. This experiment enhances our understanding of digital logic circuits and their applications.
