Title:
デジタルデータ記録装置、及び、そのサンプリングデータ特定方法並びにサンプリングデータ特定用プログラム
Document Type and Number:
Japanese Patent JP4128191
Kind Code:
B2
Abstract:
A digital data recording apparatus, which can record the exact acquisition time of data, a sampling data identification method thereof, and a program for identifying sampling data, are provided. A CPU 11 reads out the program of a first conversion formula. The CPU 11 uses the first conversion formula to convert a time series of detection temperature data into a time series of actual oscillation frequencies f'' of a reference clock signal. At a subsequent step, the CPU 11 calculates the respective normal sampling timings employing the current time as a reference time by dividing a time series of count values by each of the actual oscillation frequencies f'' corresponding to the respective count values.
