On the Design of a Differential Filter using FIR Narrow Band Filters
Yasuo Tachibana (KAIT)
Abstract (in Japanese) (See Japanese page) 
(in English) The processing of FFT for the sequence weighted by the extended Hanning window is equivalent to many narrow band FIR filters with different center frequencies. In this paper we propose a design method of differential filters with several orders from zero to the adequate value by the liner combination of these narrow band filters. Some constraints on the coefficients of the proposed filter are provided in order to justify the differential property for the signal with very low frequency. The solution is expressed by the Penrose generalized inverse. It is shown that our result is able to be used as the first step of the Remez algorithm in the low pass case. By the proposed method we obtain the Chebyshev approximation filter. Some numerical examples are presented.
