What is IIR low-pass filter?

This filter has an exponential impulse response characterized by an RC time constant. Because the exponential function is asymptotic to a limit, and thus never settles at a fixed value, the response is considered infinite. IIR filters may be implemented as either analog or digital filters.

Is a low-pass filter FIR or IIR?

FIR filters are mainly used in bandpass and bandstop filtering applications. While low pass and anti-aliasing filtering applications require IIR digital filters.
