Since the filter coefficients are the impulse response, you should be able to do a DFT of the coefficients to get the frequency response.

What I would like (but not essential) is the ability to take my filter coefficients and validate them with another program. I don't see this in ScopeFIR, although I could possible write my own code to do what I want I need to validate my filters with a program not created by my own fair hands :-) With a filter covering 0 to 4,000Hz I simply feed a signal in, see what I get out and do some sums...
