Description: IIR design concept is as follows: according to the parameters of the filter to be designed to determine the transfer function of an analog filter, and then according to this transfer function, the digital filter is designed by bilinear transformation or pulse response invariant method.Fir: finite impulse response filter. It means that the impulse response is finite. Compared with IIR, it has the advantages of linear phase and easy design. This shows that IIR filter has the disadvantage of phase non-linearity and is not easy to design. On the other hand, IIR has the disadvantage that fir does not have, that is, fir needs more parameters than IIR when designing the same parameters of filter. This means that the calculation of DSP should be increased. DSP needs more computing time, which affects the real-time performance of DSP.
