Title:
DIGITAL SIGNAL PROCESSING DEVICE AND DIGITAL SIGNAL PROCESSING PROGRAM
Document Type and Number:
Japanese Patent JP2020080517
Kind Code:
A
Abstract:
To provide a digital signal processing device capable of outputting a normal digital signal even if a digital signal output from a digital filter is not normal.SOLUTION: Digital signal processing devices 10, 10a include: digital filter units 102, 103, 104, 105 for performing a filtering process on an input digital signal to output a digital signal after filtering; a processing determination unit 106 for determining whether the digital signals output by the digital filter units 102, 103, 104, 105 are normal signals; and a processing control unit 107 for determining digital signals input to the digital filter units 102, 103, 104, 105 as digital signals to be input to a subsequent stage when the processing determination unit 106 determines that the digital signals output by the digital filter units 102, 103, 104, 105 are not normal signals.SELECTED DRAWING: Figure 1
