The analogue, differential input signals (Vx) are connected to the integrator the whole time and one of two reference voltages (V1, V2) is alternately connected to the integrator also the whole time. A comparator (1) reads off the integrator polarity and generates a digital signal which is used by a component (2) for time measurement, calculation and re-coupling. The component controls the coupling of the reference voltages to the integrator and records the times during which the reference voltages are connected. The component also records the time points at which the comparator digital signal changes the situation and carries out the calculations starting from these times. The differential input signals are fed to the integrator via a two-pole converter (7) for changing their polarity. |
