Hi, I have a given Magnitude Response H(f) which is derived from an analytical equation. Now I want to amplify/damp my Signal x(t) with it, but I don't really know how. If I can get the z-Transform of my curve, I could filter my Signal. Or maybe I should design a filter somehow which fits my curve best. Any advice is appreciated. Cheers
