ABSTRACT:
The present invention relates to an apparatus for measuring the level of a signal voltage supplied to the control input of a controllable constant current source whose output is connected to a phase inverting circuit conducting in one direction and to a rectifier conducting in the opposite direction so that a full-wave rectified current is obtained which is adapted to flow through a measurement device in order to obtain a measure of the voltage level.
