摘要
带通信号处理技术，广泛用于通信、雷达等领域。随着数字技术的发展，人们越来越希望在射频端实现数字处理。但是数字信号处理却远远不能跟上，而对带通信号的欠采样技术，则使中频乃至射频数字处理成为可能。本文将综述、讨论带通均匀欠采样技术及一些应用。
Digital signal processing of bandpass signal is widely used in communications radar etc As the development of digital signal processing it is desired to implement RF digital processing But the bottleneck is the digital signal processer(DSP) The techniques of undersampling of bandpass signal make the realization of IF even RF digital signal processing possible This paper summarises the techniques of undersampling of bandpass signal and their applications
