Abstract

PURPOSE:To execute a digital integration satisfactorily, by adding constant offset voltage to an input voltage signal which is varied extending over positive and negative ranges, outputting it as a signal which is varied in only the positive range, converting it to a frequency signal, counting it, and subtracting and correcting the offset voltage portion. CONSTITUTION:An input signal from a preamplifier 100 is sent to an addeer 210 of a bipolar digital integrator 200, and a constant offset voltage signal is added. This voltage signal is outputted as a signal which is varied in only the positive range, is converted to frequency by a frequency converter 220, and is counted by a counter 230. Its output is inputted to a control computer system 300, and from the system 300 to the integrator 200 are provided control signals such as integration start, integration stop, initial value setting, etc. In this way, even when an input level of a bipolar analog input signal is near zero, a digital integration is executed without losing a follow-up property to an input variation.
