[QUOTE="Mark DeArman, post: 147999, member: 950"] Re: FIR filters Filtering something, by convolving it with anything, then reversing time and doing it again, results in zero phase. It's not about IIR or FIR. Haha, you make it sound so easy ;-) I've never seen an implementation of real-time processing in the FT domain, but I would assume the issues arise from reverseability of the FT operation. I think you are mistaken about which one is more computationally expensive for practical lengths, but the traditional FIR implementation are definitely delay expensive, and connected directly to the sample rate. I do have a sample project from the now defunct Analog Devices automotive group from years ago if anyone is interested in checking it out. [/QUOTE]
