The concept of FIR and IIR has been bothering me for some time now. I am unable to understand how and why any response (what to speak of impulse response) can be of infinite length. It has to decay over the period of time. I read that for IIR, the response does not end. This is not very clear. Also can anybody explain how the concept of FIR was conceived? (prime motivation)
