Abstract

The purpose of this paper is to suggest a construction method of IIR Digital Filter by using a parallel connection of the First and Second dimension of wavelet function with APF and delayer. According to Mallat, it is known that the wavelet function is closely connected with filter bank, and that there are many ways of extracting wavelet function out of a complete reconstructive filter bank. These methods, however, are mostly based upon FIR Digital Filter. Therefore there is only a few ways of using IIR Digital Filter. The advantage of using IIR Filter is that it decreases order comparing to FIR Filter. Also, it satisfies the orthogonal condition which extracts the orthogonal wavelet function. In order to satisfy the regularity conditions of wavelet function, this paper deals with the extracting method from a new First and Second dimension of a recursive wavelet function by adding the Maximally Flat.
