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.
One advantage of FIR filters is stability. They are stable because they do not rely on feedback. Another notable quality these filters have are their ability to function at many frequencies.
1)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. 2)IIR is not always stable but FIR is always stable. 3)FIR can have precisely linear phase while IIR filters do not have linear phase.
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.
SAnd is used in sand filters. rocks are not used in pool filters.
