Abstract

PURPOSE:To secure the stability and the response property of a servo system, by controlling the voltage dividing ratio of a voltage divider, dividing the voltages of an input signal for a notch filter circuit and the output signal from the notch filter circuit. CONSTITUTION:An input signal 11 is connected to a notch filter circuit 101 and one input terminal of a voltage divider 102. An output signal 12 from the notch filter circuit 101 is connected to the other input terminal of the voltage divider 102. The voltage divider 102 outputs a signal 13, in which the voltages of the input signal 11 and the output signal 12 are divided with a predetermined ratio. According to this method, the stability and the response property of a servo system may be secured even when a central frequency is set in a comparatively low frequency band.
