FIR Filter
Define FIR (Finite Impulse Response) filter h(n) with N number of samples:
(Matlab Simulink file)
IIR Filter
Direct Form 1
Define IIR (Infinite Impulse Response) filter with of N number of numerator coefficients and M number of denominator coefficients:
(a0 = 1)
Direct Form 2
Direct form 2 is a second alternative to implementing IIR filter implementation. The theory is based on splitting the system is into separate blocks:
