デジタル信号処理装置、デジタル信号処理方法及びデジタル信号処理プログラム
Document Type and Number:
Japanese Patent JP5092580
Kind Code:
B2
Abstract:
The present invention provides a digital signal processing device that considerably reduces a return noise generated in a processing result signal in specific signal processing without wastefully increasing the processing load. There is provided a digital signal processing device that executes specific signal processing under which a return noise is generated in a processing result signal which includes an up-sampling processing unit that performs the up-sampling processing for a digital signal with a predetermined up-sampling rate to generate an up-sampling signal, a specific signal processing unit that performs the specific signal processing for the up-sampling signal generated by the up-sampling processing unit to generate the processing result signal, and a down-sampling processing unit that performs the down-sampling processing for the processing result signal generated by the specific signal processing unit with a predetermined down-sampling rate to generate a down-sampling signal.
