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 a filter control unit which outputs an adjustment signal which adjusts an order of the decimation filter on the basis of a characteristic of the input signal; and a signal processing apparatus which performs signal processing, which corresponds to the adjustment signal, on the output signal of the decimation filter.
Claims20
A signal processing system comprising:
- an adaptive decimation filter apparatus which has a decimation filter which outputs an output signal obtained by down-sampling an input signal, and a filter control unit which outputs an adjustment signal which adjusts an order of the decimation filter on a basis of a characteristic of the input signal;
- and
- a signal processing apparatus which performs signal processing, which corresponds to the adjustment signal, on the output signal of the decimation filter.
A signal processing method comprising:
- outputting, by a decimation filter, an output signal obtained by down-sampling an input signal;
- outputting, by a filter control unit, an adjustment signal which adjusts an order of the decimation filter on a basis of a characteristic of the input signal;
- and
- performing, by a signal processing apparatus, signal processing, which corresponds to the adjustment signal, on the output signal of the decimation filter.
A non-transitory computer readable medium having recorded thereon a signal processing program that, when executed by a computer, causes the computer to function as:
- an adaptive decimation filter apparatus which has a decimation filter which outputs an output signal obtained by down-sampling an input signal, and a filter control unit which outputs an adjustment signal which adjusts an order of the decimation filter on a basis of a characteristic of the input signal;
- and
- a signal processing apparatus which performs signal processing, which corresponds to the adjustment signal, on the output signal of the decimation filter.
