No, in software. for brevity I would like to reframe my question.
I would like to know the algorthm and also the concept of designing FIR filters. So that I can do it myself without depending on any third party software.
A classical design method is based on the inverse fourier transform of the frequency repsonse, multiplied with a window function. I think, it's called "direct" synthesis or something similar.

nice, thanks. But, can you please tell how to find the FFT so that it gives the FIR co efficients?. I am actually from mathematical background. Please guide me in understanding Fourier transform. I know only the integral which needs to be find out to find fourier transform( it is a definite integral from -infinity to + infinity. How it gives the fourier co-efficients? if passible please give usefull links
U should use the method of using a window based design, use a kaiser window and set a sampling rate, bandwidth, attenuation. Compute the group delay using mathematical computations. Refer Proakis for designing FIR filter and u will get some nice ideas.
