Infinite impulse response (IIR)

Infinite impulse response (IIR) filters are [filters] whose [impulse response] design involves feedback

• IR approaches but never reaches zero
• unstable, can self-oscillate (analog) or output explosive values ([digital])
• this feedback enables amplification of the [spectrum] (i.e. [additive EQ])
