摘要：The invention concerns a signal processor for processing a digital input signalcomprising samples sampled at a sampling frequency, the signal processor comprising aplurality of filters (106, 108) arranged to divide the digital input signal into a first signal ina first frequency band below a first cut-off frequency, and a second signal in a second

frequency band above a second cut-off frequency; first frequency shifting circuitry (110)arranged to shift the second signal to a frequency band below the first cut-off frequency;decimation circuitry (116, 118) arranged to decimate the first signal and the shiftedsecond signal; and processing circuitry (120, 122) arranged to process the decimated firstand second signals.
