Short Content:     The FIR filter's structure main right and wrong recursive structure, has not output the input the feedback. And the FIR filter are very easy to obtain the strict linear phase characteristic, avoids processing the signal to produce the phase distortion. But the linear phase manifests in the time domain is merely h (n) in the time detention, this characteristic in profile transmission systems and so on image signal processing, data transmission is very important. In addition, he will not ...
