Document Type and Number:
WIPO Patent Application WO/2023/032472
Kind Code:
A1
Abstract:
The present invention provides a signal-processing system comprising: an adaptive decimation filter device having a decimation filter that outputs an output signal obtained by down-sampling an input signal, and a filter control unit that outputs an adjustment signal that adjusts the order of the decimation filter on the basis of the input signal characteristics; and a signal-processing device that performs signal processing according to the adjustment signal for the output signal of the decimation filter.
