Abstract
Provided is a signal processing system including: an adaptive decimation filter apparatus which has a decimation filter which outputs an output signal obtained by down-sampling an input signal, and an aliasing noise detection unit which detects a magnitude of aliasing noise, which is folded back to a frequency lower than a Nyquist frequency in the output signal of the decimation filter by the down-sampling; and a signal processing apparatus which has a filter control unit which adjusts an order of the decimation filter on the basis of the magnitude of the aliasing noise, and an adaptive filter unit which performs filter processing on the output signal of the decimation filter.
