SIGNAL PROCESSING DEVICE AND METHOD

摘要

The present invention relates to a signal processing device and method. The device receives, from a sensor which measures a physical quantity applied thereto and outputs an accumulated or integrated value of the physical quantity as an M-bit digital value, the digital value, and, when a difference between the physical quantities at two successive data acquisition times lies within a predetermined range and an absolute value of a digital counter increment is greater than 2M-1, calculate the digital counter increment as the physical quantity measured by the sensor.
