METHOD FOR SETTING AND DEVICE FOR SETTING FREQUENCY RESPONSE FOR FILTER

摘要

A method for setting the frequency response for a filter is provided with a step for dividing a target frequency band into a plurality of first partial bands at frequencies for intersections of a first line showing a target spectrum envelope and a second line showing a first spectrum envelope wherein a measured frequency spectrum is smoothed, and a step for setting a filter frequency response for the first partial band indicated by an operator according to setting operation by the operator for an amount of adjustment for the first partial band from among the plurality of first partial bands.
