Title:
DATA PROCESSOR FOR SPECTROPHOTOMETER
Document Type and Number:
Japanese Patent JPS63293429
Kind Code:
A
Abstract:
PURPOSE:To obtain accurate measurement data at a relatively low cost by controlling a sampling period in accordance with the gradients detected by a data gradient detection section. CONSTITUTION:A measurement input signal 1 which is an analog signal is inputted from the detection section to an A/D converter 2. The converter 2 converts the measurement signal to a digital signal in accordance with the sampling period from a CPU 3 and outputs said signal. The CPU 3 executes data processing in accordance with the program previously stored in a ROM 4. Namely, the CPU 3 samples and takes in the data from the A/D converter 2 according to the program and controls the switching of the sampling period in such a manner as to shorten the period if the inclination of the data is steep and to prolong the period if the inclination of the data is gentle. The high- accuracy data of a large number of data for the part of the steep inclination of nay time course curve is thereby taken and the accurate data is obtainable.
