Web1 day ago · Infinite Impulse Response Filter. An infinite impulse response (IIR) filter uses current and past input values as well as past output values in its calculation, i.e., it uses feedback and hence is recursive. As a result, the filter response in the time domain to a unit pulse input is infinite (see Section 2 of [2] for additional details). WebDec 17, 2024 · Your calculation is correct. Your signal has its energy equally distributed in all frequencies. But note that in discrete-time, "all frequencies" means from $\omega = …
