IIR Filter Test

This app makes it possible to freely specify the coefficients a(i) and b(i) and then display them graphically. The step response of the transfer function of the 2nd order IIR filter is shown. This allows all classic transfer functions to be represented. The big advantage of the app is that you can preselect the type of transfer function and then test your own changes to the parameters quickly and easily. This is certainly unique here in the store.
