![]() ![]() You may know that a certain expression in s can describe a specific filter. In Mathcad look up the butter(), cheby1(), cheby2(), and bessel() functions in combination with iirlow(), iirhigh(), iirpass() and iirstop(). On the other hand I know that both Mathcad and Matlab have functions that allow you to calculate the response in time on a signal through a filter that is described by your expression in s. I'm convinced that neither Mathcad, nor Matlab will give you the inverse Laplace tranform of the expression in s that you gave, based on the fact that Mathematica cannot give it and I didn't find it in my textbooks. ![]() Your reaction suggests to me that you have an incorrect understanding of what Mathcad, and Matlab, can deliver. ![]()
