Abstract
Digital integrators and differentiators are an integral part of many systems like control, communications, audio, medical, and DSP in general. Both digital integrators and differentiators can be classified as finite impulse response (FIR) or infinite impulse response (IIR) filters. IIR digital solutions are preferred because their implementation is simpler, and they have much better magnitude response. However, their phase characteristics are not linear in comparison with FIR filters, which can cause problems in some applications. The frequency response of an ideal integrator is
