本文介绍了阻带等小值、通带等纹波RC多相滤光片元件值的数值设计方法。据作者所知，具有等纹波特性的RC多相滤波器元件值的确定一直没有得到解决。有一篇论文研究了这个问题，但它只能通过数值计算给出次优解[3]。利用系数匹配法，提出了阻带和通带均具有等纹波增益的RC多相滤波器的数值设计方法。文中给出了一些设计实例。
This paper describes a numerical design procedure of element values of RC polyphase filters with equal minima in stopband and equal ripple in passband. Determination of element values of RC polyphase filters with equal-ripple characteristic have not been solved to the best knowledge of the authors. There found a paper tackling with the problem; however, it can only give sub-optimal solutions via numerical calculation [3]. We propose a numerical element value design procedure for RC polyphase filters with equi-ripple gain in both stopband and passband by using the coefficient matching method. Some design examples are given.
