A METHOD TO DETECT SUDDEN CHANGES IN SIGNALS

Heikki Jokinen
  • Abstract:
    Measurements may contain disturbances like transients or abrupt level changes. Although the duration of these effects is often short, the computed results derived from the measurements may be heavily corrupted. In order to be able to analyse only the non-disturbed region of the signal, the detection of anomalies is needed. In this paper we introduce a method for detecting sudden changes applying windowed moving variance computation technique.
