Abstract

A method is distinguished in that outside of the analog/digital converter, on the basis of an analog signal (UA) to be digitized by the analog/digital converter, a sequence of digital pulses (P2) is generated, of which at least the width or the repetition frequency is analog signal-dependent, and that a digital result determined based on the pulse sequence and the digital value generated on the basis of the same analog signal by the analog to digital converter are checked for conformance with one another. As such, in a simple manner, a continuous monitoring of the A/D converter to be monitored is rendered possible during its "normal" operation.
