摘要
本文建立了任意通带信号的采样定理,对附有直流分量的带通信号、几个带通的组合、或者若干个带通与带限组合等等这类组合带信号,给出最低采样率的算法,可直接用于数据表示和数据压缩等相关问题。
A sampling theorem for signals in arbitrary passband is proposed and the efficient algorithm to solve the least sampling rate is given, which can be applied to signal representation based on its channel pattern.
