It gives IIR o/p but not always.

Ex: y(n) = x(n) – x(n-3) + y(n-1)

FIR filtersIIR filters
1. Linear phase no phase distortion.Linear phase, phase distortion.
2. Used in speech processing, data transmission & correlation processingGraphic equalizers for digital audio, tone generators filters for digital telephone
3. Realized non recursively.Realized recursively.
4. stable

Stable or unstable.

H(n) = an u(n)   a<1 stable

=  0          a>1 unstable

5. filter order is moreLess
6. more co-efficient storageLess storage
7. Quantization noise due to finite precision arithmetic can be made negligibleQuantization noise
8. Co-efficient accuracy problem isMore
less severe 
9. used in multirate DSP (variable sampling rate)
