Abstract
PURPOSE: To make it possible to input a high-precision analog value by correcting a dynamic error, occurring in a noise filter, at any time during an analog data measurement.
CONSTITUTION: From a difference of a digital value, obtained by A/D-converting an analog signal, between its sampling points, the gradient of the input signal is detected 21 and from the previously-known time delay of a noise filter, a dynamic error is calculated 22; and this error value is added to the input value by correcting device 23 to make a correction of the dynamic error.
