Langzeitintegrator fuer eine Spannungsquelle kleiner Spannung

摘要

In a long-time integrator for a voltage source of low voltage, the voltage source is connected to the input of a monolithic dual-slope integrator in which an electronic stepping down device with a downstream mechanical counter is connected to the output conducting the oscillator pulses and a gate circuit which gates the electronic stepping down device is connected to an output of the dual-slope integrator in such a way that a stepping down signal is emitted in each case during the integration period.
