Abstract
A digital filter setting device, a control method of the digital filter setting device, and a recording medium are provided. Filter characteristics of a digital filter after parameter setting are easily recognized by a user. A digital filter setting device (1) includes: a parameter setting part (11) receiving input of filter parameters; a step response time calculation part (14) calculating a step response time of the digital filter in a case that the filter parameters are set; and a graph generating part (12) displaying the calculated step response time in the form of graph.
Claims18
A digital filter setting device which sets filter parameters of a digital filter device that performs a filter processing to an input analog signal by a digital filter, comprising:
- an input receiving part receiving input of the filter parameters;
- a filter characteristic calculation part calculating a step response time as a filter characteristic of the digital filter when the filter parameters received by the input receiving part are set;
- and
- a graph display part displaying the calculated step response time in a form of graph on a display part.
A control method of a digital filter setting device which sets filter parameters of a digital filter device for performing a filter processing to an input analog signal by the digital filter, comprising:
- an input receiving step for receiving input of the filter parameters;
- a filter characteristic calculation step for calculating a step response time as a filter characteristic of the digital filter when the filter parameters received by the input receiving part are set;
- and
- a graph display step for displaying the calculated step response time in a form of graph on a display part.
