摘要：This work discussed the design steps of digital filter and methods of transformation from analog domain to digital domain. In order to use computer to solve the problem of recursive function whose order is N, this work derivates a transformed algorithm. The proposed scheme shifts system transformation to a coefficient matrix and a variable matrix. This work explains how to fix coefficient matrix and a variable matrix in detail. And at last, it takes advantage of feasibility and validity of simulation algorithm to verify it. The merits are as follows. First, it is very direct and it applies the calculation between matrix and matrix. And second, it is very general, so no matter it is from simulative low pass to digital low pass, or from simulative high pass to digital high pass, or from simulative band pass to digital band pass, this method can be used. Third, it is the fastest since there are fewest numbers of calculations.
