ABSTRACT:
The invention concerns a method for filtering signals (Vin) generated by a piezo-electric type accelerometer in response to detection of a shock applied to an object to which the accelerometer is connected, this method characterised in that it ensures, during a particular step, that the signal (Vin) generated by the accelerometer, after having increased and exceeded a first threshold value (VTH,ON) decreases and becomes lower than a second threshold value (VTH,OFF) lower than the first threshold value (VTH,ON) after a period of time (TP,ON) greater than a minimum period of time (TP,ON,MIN) and less than a maximum period of time (TP,ON,MAX). The invention also concerns a device for filtering signals generated by an accelerometer in response to detection of a shock applied to an object connected to the accelerometer. Finally, the invention concerns a portable object such as a wristwatch including a detection device of this kind.
