Abstract

PURPOSE: To dispense with external processor by which the peak value is obtained by operating a comparator on the basis of the past peak value, which is stored in the memory, as a reference value.
CONSTITUTION: The A/D converter 3 converts an input analog signal into a digital data. The digital data is stored as a peak value by the memory 4' that is given a storing operation signal from the control signal generator 7. The data is displayed by the indicator 8 and taken from the terminal 9, and is converted into an analog data by the D/A converter 6 again. the comparator 2 compares the analog output from the D/A converter 6 with the input analog signal that is applied to the terminal 1, and its output is applied to the control signal generator 7. The peak value of the input signal is stored in the memory 4' by the output of the control signal generator 7.
