METHOD FOR PROCESSING AND STORING SENSOR SIGNALS, AND A CORRESPONDINGLY DESIGNED SIGNAL DETECTION DEVICE

摘要

The acceleration sensor output signal is firstly shifted to a lower level by subtracting an offset value and/or a value deviating from the zero point by an interval, and is subsequently multiplied by a factor greater than 1 so that the range of the sensor useful signal level is expanded. The multiplied value is then stored with a reduced number of bits. This reduces the memory requirements without or with only minimal loss of resolution.
