Signal evaluation for movement detector

摘要

The method involves producing a signal course characteristic of a recorded change, in which an interference signal is sampled. The interference signal has a fast rising slope rate in comparison to a movement signal. The signal evaluation is preferably interrupted by a detected interference signal, preferably within a time interval which is larger than the pulse duration of the interference signal. Preferably the interference signal has a rise time which is less than 1 microsecond.
