摘要：In a data acquisition system of ADC system, a log amplifier is provided at thepre-stage of an A/D converter, a signal amplified by the log amplifier having a nonlinearinput-output characteristic is A/D-converted, and an adding operation of data is
performed while reconverting a voltage value data which is converted to a nonlinearcharacteristic to data with a linear scale according to a table memory for reverse-logconversion. A known voltage value is inputted into the log amplifier to perform
measurement, and calibration of the table memory is performed by storing the voltagevalue and the voltage value data after A/D-converted.
