本文对数字多相网络的理论提出了一些个人的见解,并详细论证了这些基本原理。文章说明了由这种多相网络与一些特殊形式的DFT处理器级联可以形成一个数字带通滤波器系列,从而在TDM/FDM变换中起了一定的作用。
This paper presents some personal insights into the theory of digital polyphase networks and demonstrates in detail these basic principles. The article shows that a series of digital band-pass filters can be formed by the cascading of this multiphase network with some special form of DFT processors and thus play a role in the TDM / FDM transformation.
