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).

WebThe dirac delta function and unit impulse are shown in Figure 9(a) and 9(b) respectively. The impulse function has some special properties. The sampling property. Another important property is the scaling property. Since the derivative of the unit step u(t) is zero everywhere except at t=0, the unit impulse is zero everywhere except at t=0.
