Logic Gates :-

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.

    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.

Logic Gates

Logic gates as discussed in the Computer Science and Computer Architectures [CSCA] course at the University of Applied Sciences CAMPUS 02, Graz, Austria.

The project features the following circuits:

• Basic Logic Gates - demonstrates behavior of the five basic logic gates. [learn more]
• Controlling Gates - demonstrates how signal propagation can be controlled by "opening" and "closing" the gates.
• Combining Gates - demonstrates how logic gates can be combined to implement an arbitrary boolean function. [learn more]
• 2-Bit Comparator - developed based on it's truth table by using the NOT, AND, and OR Gates.
• 2x2-Bit Comparator - developed by using the 2-Bit Comparator.
• 2-Bit Adder - developed by using the 2-Bit Comparator and basic logic gates. [learn more]
