Experiment 1:

Testing truth table values for logic gate combinations

Fundamental Gates...

Experiment 3

Universality of NOR and NAND Gates and the De Morgan's Theorem in action

Logic gates are the basic building blocks of any digital system. It is an electronic circuit having one or more than one input and only one output. The relationship between the input and the output is based on a certain logic.

Logic gates are named as :

- AND Gate
- OR Gate
- NOR Gate
- NAND Gate
- XOR Gate
- XNOR Gate
- NOT Gate

ASSIGNMENT :

In the given assignment I have to verify all the logic gates and hence I had used digital led for it.

- Digital LED :

Digital LED is used for verification of circuit in digital electronics. It glows when circuit gives a true value and do not glows when the value is false.

In this assignment when the value will be true i.e., output will be 1 LED will glow with red color and else it will be shown in a white transparent color.

- AND Gate :

2. OR Gate :

3. NOT Gate:

4. NAND Gate :

5. NOR Gate:

6. XOR Gate:

7. XNOR Gate:

** All the diagrams and truth tables I had used above is formed using tools provided in simulator.

This is a project for the verification of boolean laws or logic gates.

sample input

A2A1A0= 110

B2B1B0= 101

expected output

S2S1S0 = 011, C3= 1
