ABSTRACT:
The device comprises a transducer which supplies, in response to an exciting signal, a detection signal that is representative of its angular speed, and a circuit which responds to this detection signal to supply an angular speed measurement signal. For this measurement signal to be readily usable regardless of the transducer, the circuit measures the phase difference between the detection signal and the exciting signal, this phase difference being representative of the angular speed of the transducer.
