Abstract

PURPOSE: To simplify the operation, by suitably deciding the timing which sampling-holds the input data fed from the measured system, counter operation of the address counter for address designation of the input data memory, and the timing to read in the input data.
CONSTITUTION: The timing set of the sample hold circuit 22 which sample-holds the input data fed from the measured system 20, count operation of the address counter 28 for address designation of the input data memory 24, and the timing set to read in the input data in sample holding to the input data memory 24 after A/D conversion at the A/D converter 23, are determined such that the definite width of pulse shorter than the sampling period is produced from negative time and almost the center of the definite width of pulse is at zero.
