Scrive ian esten <de...@cu...>: > the impulse response of a filter completely describes its frequency > response... what other information do you need? I agree. What noise are you refering to ? Mark said he recorded the output via digital audio link (Protools) and the original sample (non filtered) show all samples zero except one. So don't understand where the noise source could lie (except perhaps in a wrong GSt setting ?). Steve please show the iFFT of the impulses in a logarithmic scale. ( at least the y-axis (in dB) The graphs you posted are impossible to read. Perhaps it looks much better in the log scale ? Let us know please.
