PURPOSE:To reduce the burden of design and development work by calculating a parts constant based on an inputted frequency characteristic constant and switching the parts constant of an evaluating equalizer in accordance with this calculated parts constant. CONSTITUTION:A parts constant calculating part 9a which calculates the parts constant of an evaluating equalizer 12 based on the frequency characteristic constant inputted from an input part 8 and outputs parts constant data and a parts constant switching control part 18 which controls switching of the parts constant of the evaluating equalizer in accordance with parts constant data are provided. The parts constant is calculated based on the frequency characteristic constant inputted from the input part 8, and the pats constant of the evaluating equalizer is switched in accordance with the calculated parts constant. Thus, parts constant data is obtained without manually calculating the parts constant, and this device is variously used to eliminate a need of building-in and replacement work of parts required for preparation of actual machine evaluation. |
