Abstract

PURPOSE:To sense the waveform accurately, by sensing starting and finishing points based on the difference between the groups wherein sampling data are summed up for every specified number, and increasing the specified number of the data in response to the repeating sequence of the peaks. CONSTITUTION:A signal has the waveform which has repeatedly occurring peaks and whose inclination of the slope decreases in response to the repeating sequence. For example, the output signal waveforms of a gaschromatograph device are sample at a constant period. The obtained neighboring sampling data are summed up for every specified number, and a plurality of data groups are obtained. The difference between neighboring data groups is obtained. The starting point of the waveform at every peak is sensed by the face that said difference exceeds the preset starting sensing value. The finishing point is sensed by the fact that said difference becomes lower than the preset finish sensing value. At the same time, the specified number of the sampling in response to the repeating sequence of the peaks.
