IIR filters rely on past inputs and past outputs. They mimic analog filters and achieve sharp roll-offs with far fewer coefficients than FIR filters. The trade-off is potential instability, phase non-linearity, and susceptibility to quantization noise issues like limit cycles. The difference equation for an IIR filter is:
