摘要：A signal processor for processing a digital input signal including samplessampled at a sampling frequency, the signal processor comprising a plurality of filtersarranged to divide the digital input signal into a first signal in a first frequency bandbelow a first cut-off frequency, and a second signal in a second frequency band above a
second cut-off frequency; first frequency shifting circuitry arranged to shift the secondsignal to a frequency band below the first cut-off frequency; decimation circuitryarranged to decimate the first signal and the shifted second signal; and processingcircuitry arranged to process the decimated first and second signals.
