Hello all, I was wondering what is the benefit of a SYMMETRIC impulse response for a filter? Lets assume that we have an FIR filter. Does a symmteric impulse response necessarily produce a linear phase response (and thus a constant group delay) over the frequency band of interest? Are there any other benefits from a filter with a symmetric impulse response? Thanks so much for your replies! _____________________________________ Do you know a company who employs DSP engineers?
