WebDigital filter For time domain simulations, the frequency dependent elements rely on either infinite impulse response (IIR) or finite impulse response (FIR) digital filters. FIR filters can provide much better … Web3 feb. 2014 · Infinite Impulse Response Filters (IIR) are the classic examples of filters used in the analog domain (and have since been digitized). These filters are referred to as IIR because of the fact that there is always a signal passing through them no matter how small. Why? Because these filters use feedback!
