The purpose of this experiment is to design a 4-bit Binary to Gray code converter using exclusive-OR gates.

The input to the 4-bit binary-to-Gray code converter circuit is a 4-bit binary and the output is a 4-bit Gray code. There are 16 possible combinations of 4-bit binary input and all of them are valid. Hence no don’t cares.The 4-bit binary and the corresponding Gray code are shown in the conversion table. From the conversion table, we observe that the expression for the outputs G4,G3,G2 and G1 are as follows:

The minimal expressions for the outputs obtained from the K-map are:>

Components used:

We used the following components for this experiment-

1. IC 7486

How to make connection:

After Starting the experiment first click on the Components button to get component list. Now you can Drag and Drop any component in the circuit designing area. To make connection between components, just click on the Blue bubble of any components and Drag it to another Blue bubble of the same or any other components. To delete connection or to remove any component use Double click on that component or connection.

How to run:

After connenting all the required components,click on the Start button and you will get a new start window, where you can give the inputs. After this,you click the run button and finally the outputs are shown.
