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 −

- The output of combinational circuit at any instant of time, depends only on the levels present at input terminals.

- The combinational circuit do not use any memory. The previous state of input does not have any effect on the present state of the circuit.

- A combinational circuit can have an n number of inputs and m number of outputs.

ASSIGNMENT :-

In this assignment I am working on designing and simulating the given boolean function ( Z=X'Y+X'Y' ).

- Truth table for given function :

- Design of circuit using gates :

* Formed using manual inputs and outputs using simulator.

- Circuit on simulation :

* Formed using combinational analysis tool in simulator.

Implementation of a 2:1 MUX using Basic Gates

HA(Half Adder), a combinational circuit, constructed using one X-OR and one AND Gates.

Outputs are the SUM upper one and the CARRY the lower one.

Full Adder using 2 X-OR, 2 AND and 1 OR Gates.
