ABSTRACT:
An angular rate detector includes an oscillator having a first terminal to which a drive voltage is applied, a second terminal where a signal occurs having a given phase displacement with respect to a signal appearing at the first terminal during a resonance of the oscillator and a third terminal where a signal occurs having a phase which changes in accordance with an angular rate. An oscillator is provided for producing an alternating signal which corresponds to the drive voltage applied to the first terminal in accordance with the signal appearing at the second terminal. A frequency multiplier responsive to a signal which corresponds to the oscillation frequency of the oscillator produces a clock pulse having a frequency higher than the oscillation frequency. A phase difference pulse signal is produced having a duty cycle which changes in accordance with a phase difference between the signal occurring at the third terminal of the oscillator and either the signal applied to the first terminal or the signal occurring at the second terminal. A counter is provided for counting the clock pulses during a time interval when the phase difference pulse signal assumes either a high or a low level.
