Difference between FIR (Finite Implulse Response) and IIR (Infinite Impulse Response) filters?:

FIR	IIR
Linear Phase Response	Nonlinear Phase Response
Group delay is better	Gourp delay is not good
More memory	Less Memory
Only depends on Input	Depends on both input and output
Only zeros	both zeros and poles (numerator and denumerator)
Easy to implement	Difficunt to implement
Tapping high order	Tapping lower order

FIR filter: 

1) Open Matlab "filterdesigner" --> Get coefficients --> change filter structure to get nominator and denominator for IIR

2) Load FIR and IIR MATLAB Simulink models

3) Replace coefficients

IIR Filter:
