DIGITAL DATA RECORDING DEVICE, ITS SAMPLING DATA SPECIFYING METHOD, AND PROGRAM FOR SAMPLING DATA SPECIFICATION

摘要

PROBLEM TO BE SOLVED: To provide a digital data recording device for recording accurate acquisition time of data, and to provide its sampling data specifying method and a program for sampling data specification.;SOLUTION: CPU 11 reads a first conversion expression program by S2 to convert the time series of detection temperature data into the time series of a practical oscillation frequency f" of a reference clock signal S2, by using the first conversion expression. Normal sampling timing is calculated, by dividing each practical oscillation frequency f", corresponding to respective counted values to the time series of the counted value by S3 and regarding the current time as the reference time.;COPYRIGHT: (C)2007,JPO&INPIT
