Abstract
A gyro includes piezoelectric force transducers which are oscillator driven. As the gyro undergoes angular displacement, the oscillators 'follow' the instant natural frequency of the transducers and FM signals are generated at the oscillator outputs which are processed by the present invention to produce digital signals proportional to gyro angular inputs and resolved about two axes.
