Abstract:
The present invention discloses a vibration detecting apparatus for obtaining a signal indicating the speed or displacement of an object by integrating a signal generated by an acceleration meter or a speed-meter, equipped with an integrator with a variable lower limit frequency of the integrable frequency range or bandwidth, and a control unit for varying the lower limit frequency of the integrator according to a predetermined method in response to the input and/or output of the integrator.
