THE SAMPLING THEOREM FOR BANDPASS SIGNAL AND THE DESIGN OF ALL DIGITAL QUADRATURE DETECTORS
Atr La · JOURNAL OF ELECTRONICS INFORMATION TECHNOLOGY · 1999
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.
