UNIT AND METHOD FOR MONITORING AN INTEGRITY OF A SIGNAL PATH, SIGNAL PROCESSING SYSTEM AND SENSOR SYSTEM

摘要

A monitoring unit (100; 800) for monitoring an integrity of a signal path (200; 620) configured to receive an input signal (210, 802) and further configured to provide an output (220) in response to the input signal (210, 802), comprises a signal monitor (110; 801) configured to extract a first signal (112; 630) from the signal path (200; 620) corresponding to the input signal (210, 802) in at least a first characteristic. The monitoring unit (100; 800) further comprises a signal interface (120; 803) configured to extract a second signal (122; 631) corresponding to the output (220) in at least a second characteristic from the signal path (200; 620); and an evaluator (130) configured to determine, whether the at least first characteristic of the first signal (112; 630) corresponds to the at least second characteristic of the second signal (122; 631) according to a predefined relation.
