Abstract
A signal receiver having a frequency selective sampling detector which accepts a bandlimited analog signal and outputs uniformly spaced, digital samples of the signal's quadrature and in-phase components. The center frequency, phase reference and sample interval for the detector are derived from a single reference clock. The bandwidth of the detector is variable while maintaining the same center frequency.
