摘要
带通信号采样定理是全数字式正交检波器设计的理论基础。目前国内外相关文献关于带通信号采样定理的表述有多种形式,这将直接影响到全数字式正交检波器设计的优化。本文首先讨论带通信号采样定理,然后在此基础上研究全数字式正交检波器的优化设计。
The sampling theorem for bandpass signal is the theoretical basis for design of all digital quadrature detectors. There are various expressions for this theorem in previous references, which has greatly affected the optimum design of all digital quadrature detectors. The correct expression is introduced in this paper, and the optimum design of all digital quadrature detectors is discussed.
