Along the lines of this thread: Can someone please tell me the difference between FIR and IIR filters? I am familiar with impulse response for continuous time systems, and with transfer functions,but I have not yet covered IIR versus FIR in class, nor have I read any explanation of it yet, so I am curious. Is it just that the impulse response is time-limited?
