SIGNAL PROCESSING DEVICE AND METHOD

摘要

The present invention relates to a signal processing device and method. The device accumulates or integrates a physical quantity applied to a sensor, receives the input of a digital value from a senor that outputs at an M-bit digital value, and when a digital counter increment absolute value is greater than 2M-1 when the physical quantity difference at two successive data acquisition times lies within a predetermined range, the digital value increment is calculated as the physical quantity measured by the sensor.
