Design of Digital Filter Base on Linear Transform

摘要：

In this paper, an arithmetic method of bilinear transform is introduced, it can be used to realize the system transform from analog low pass to digital low pass,digital high pass 、band pass and band stop. The coefficient matrix can be obtained by the binomial calculation, the elements of matrix can be got only by addition and they are ruled which can be realized by computer. This bilinear transform arithmetic method is very clear, we can get the digital system transfer function by matrix transform from the numerator and denominator polynomial coefficient of analog system transfer function. Compared by the general calculation, this method is convenient 、high precision 、easy to adjust, In the automation and digital signals disposal field, it is very valuable.
