Especially, in the signal and image processing
fields of electronics, filters are most often used parts. Also, rapid advances
in digital systems have expanded the use of digital filters. Therefore, it is
very important to understand and learn the filters and calculation of their
coefficients. Thus, in this work, interactive graphical user interface software
which can be used for educational purposes and also accessible via the Internet
is designed in the MATLAB environment. 
In the software, genetic algorithm, which is one of the popular methods
in recent years, is used for designing the Finite Impulse Response (FIR)
filters. In this program, when the parameters of filter, which will be
designed, are entered by the user, the coefficients are obtained from genetic
algorithms, and many features of the filter are presented numerically and
graphically. Thus, the FIR filter design can easily be carried out for
practical or educational purposes using the software. Further, the superiority
of the genetic algorithm over the classical design in this field has been shown
by comparing the obtained filter coefficients for both methods.
