Combinational circuit is a circuit in which we combine the different gates in the circuit, for example encoder, decoder, multiplexer and demultiplexer. Some of the characteristics of combinational circuits are following −
In this assignment I am working on designing and simulating the given boolean function ( Z=X'Y+X'Y' ).
* Formed using manual inputs and outputs using simulator.
* Formed using combinational analysis tool in simulator.
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 :
In the given assignment I have to verify all the logic gates and hence I had used digital led for it.
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.
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.
Logic gate Circuits for the given expression has been verified with the truth table.
F(X,Y) = X'Y' + XY + X'Y is table 1.
The above expression can be simplified as the following two expressions.
F(X,Y) = X' + XY is table 2.
F(X,Y) = X'Y' + Y is table 3.
