Description: FIR滤波器设计，基于加权切比雪夫最佳一致逼近方法，从Fortran改写为C代码，来自胡广书编著《数字信号处理——理论、算法与实现》1997.8,清华大学出版社,P.250,471——但是还没有调通，本人花狠劲逐个字符敲出全部代码，反复校对，不知哪儿出问题了？如果只是高通或低通滤波倒是另外自编程序完成了，但这个Fortran来自国外名家，据称可对连续十个交替的通带阻带一次拟合，可书中没有介绍(书中公式有错误，而且列举方法是只针对低通或高通的M+2个交错点)。这里虽有不少FIR代码，但这方面几乎空白，有兴趣的来研究一下。-FIR design base on Chebyshev Approximation, C code(from Fortran, too many goto ), and can t work yet.

[Software Engineering] DesignandFPGAImplementationof

Description: In most cases, a bandpass filter characteristic is obtained by using a lowpass-to-bandpass frequency transformation on a known lowpass transfer function. This frequency transformation controls the location of passband edges and transfer zero frequencies completely. Using the “Vlach-Chebyshev approximation” [1] however, we are able to specify the (Chebyshev) passband limits directly, together with a free choice of transfer zero locations in the stopband. In this way it is possible to design bandpass transfer functions that cannot be obtained from lowpass functions by a frequency transformation. We think this method to be the only (and not very well known) analytical method to obtain such bandpass characteristics. We show how we designed wave digital realizations from the specification, through a VHDL description and synthesis into a Xilinx FPGA (Virtex-II).
