DEVICE AND METHOD FOR PROCESSING A DIGITAL SIGNAL

A device (10) for processing a digital signal (S9) of samples of a continuous signal sampled at a fixed sample rate. The continuous signal is representative of vibrations of a bearing having a stationary ring and a rotating ring that rotates concentrically relative to the stationary ring. The device...

Zusammenfassung:	A device (10) for processing a digital signal (S9) of samples of a continuous signal sampled at a fixed sample rate. The continuous signal is representative of vibrations of a bearing having a stationary ring and a rotating ring that rotates concentrically relative to the stationary ring. The device (10) includes a Farrow structure (15), identifying means (16), and controlling means (17). The identifying means (16) identifies moments when the rotating ring has rotated from a predetermined rotation angle from the rotation speed of the rotating ring. The control means (17) determines couples of control values from the determined moments and to control the Farrow structure (15) from the couples of control values.
