Analogue=to=digital converter has switching device for displacing switch-off point of bistable

摘要

The A/D converter includes an additional switching device for displacing the switching point of a bistable element (4) from the 'on' state to the 'off' state (switch off point) by a number of pulses of a pulse generator (5), determined by an arithmetic unit (31), in addition to the synchronisation with the pulses of the pulse generator. The arithmetic unit controls the displacement of the switch-off point of the bistable element such that the DC voltage component at an integrating capacitor is independent of a current parameter Ix.
