IPC: G01C19/56
Filed: 1983-05-25
Abstract: PURPOSE:To perform stable indication by reducing the ripple component of a detection signal, by a method wherein the speed of a rotor is detected in 180 deg.- phase difference and a voltage signal proportional to the detection signal is added to obtain a speed signal which is, in turn, differentiated to obtain an acceleration signal. CONSTITUTION:Pulse pickups 11a, 11b are attached so as to mutually form 180 deg.- phase difference and the signals A, B thereof have 180 deg.-phase difference. When the signals A, B are converted to voltage signals by frequency-voltage converters 12a, 12b and added in an amplifier 13, a speed signal is obtained. By adding signal wave forms C, D having 180 deg.-phase difference as mentioned above by the amplifier 13 having a 1/2-gain, a speed signal wave form E with an extremely reduced ripple component is obtained. As a result, almost no ripple component is also contained in the acceleration speed F obtained by differentiating the wave for E. By this method, the indication of the acceleration signal by an indicator can be stabilized.
