Measurement strengthening device for e.g. detecting monopolar input signals, has unit determining duration of measurement intervals during which work level of reference signals is applied to inverter as basis of measures for input signals

摘要

The device has a comparator (26), which is downstream of an integrator (18), for comparing integrator output signals with a threshold value. A comparator output signal, which is independent of the comparison results, is fed back as a control signal for presetting polarity changing clock to an inverter and a reference voltage source. A time measuring unit determines duration of measurement intervals during which the work level of the reference signals is applied to the inverter as basis of measures for the input signals. An independent claim is also included for a measurement strengthening method for detecting monopolar input signals and for producing digital output signals as measures for the input signal.
