The use of electronic systems is every day more common on daily life, therefore it is very important to comprehend the use of the new technology.

Electronic filters are one of the most important applications in the field, for their main function is to manipulate and modify the frequency spectrum of a given in signal to obtain a required signal that represents a specific function that a electronic system may require.

The present paper offers the reader a brief explanation about the software which was programmed using Matlab?. The software allows the user to design analogical filters and it gives the user the ease of designing such circuits without the need of any numerical calculations introducing all the data through an interface.
