1. A detecting circuit for detecting an output of a vibrating gyroscope including, a prism-shaped vibrator and piezoelectric elements formed on, at least, two side faces of the vibrator, said detecting circuit comprising:

  • an exciting signal generating circuit for exciting the vibrator by inputting the signal to said two piezoelectric elements;

    a differential circuit for detecting an output difference of said two piezoelectric elements to which the exciting signal generating circuit is connected;

    a synchronous detecting circuit for synchronizing and detecting an output signal from said differential circuit; and

    a smoothing circuit for smoothing the signal synchronized and detected by said synchronous detecting circuit.
