The impulse response of an IIR filter extends over infinite duration while the impulse response of FIR filter is stricted to finite no. of samples. Also IIR is not always stable but FIR is always stable.
IIR is infinite impulse response. FIR is finite impulse response.
We can divide filters two types based on the length of the impulse resopnse 1. FIR where the impulse responce is finite 2. IIR where the impulse response is infinite
IIR filters are recursive and FIR filters are non-recursive. Also FIR filters are linear phase and IIR filters are not; several applications are sensitive to non-linear phase (communications, medical, etc). In implementation, IIR filters require fewer taps (smaller order) and thusly are easier to implement and have fewer zeros. Also FIR filters are always stable, while IIR filters can often become unstable in implementation. The previous answer is correct about delays.
IIR Filter is one of the Digital Filters .it is used mostly in Audio Signals Processing
IIR filters have nonlinear phase characteristic which means the output of such a filter is (most likely) a deformed version of the input without the filtered frequency. On the other hand IIR filters might become unstable. So IIR filters are used, when the user is not particularly interested in the output in time-domain but only in frequency-domain, e.g. in audio applications such as speakers...
It minimizes the error between the idealized and the actual filter characteristics over the range of filter, but with the ripples in the passband.Note:Butterworth filter does not give the sufficiently good approximation across the complete passband in many cases. And the Taylor's series is often not suited to the way specifications are given to the filter.For the IIR filter, the Chebyshev error is minimized over the passband and a Taylor's series approximation atis used to determine the stopband performance. This mixture of methods in the IIR case is called the Chebyshev filter
