  • Rate measurement for anomalous trigger events
    Patent number: 7072785
    Abstract: A method and apparatus for processing anomalous trigger event conditions to provide anomalous trigger event rate measurements. The apparatus operates to identify one or more trigger events in at least one input signal IN, determine the number of events during a period of time (e.g. events per second) and provide a visual representation of this determination to a user via a display device. The visual representation may comprise an alphanumeric display, a waveform, a graphic image proximate a waveform and the like.
