Abstract
The present invention relates to a method of providing error margin information for threshold errors associated with a digital peak detector. The method comprises comparing a plurality of peak sample values associated with the digital peak detector to a threshold margin test level and incrementing a counter each time the threshold margin test level exceeds one of the plurality of peak sample values. The value associated with the counter relates to an amount of threshold margin associated with the digital peak detector. The present invention also relates to a method of providing error margin information for peak shift errors associated with a digital peak detector. The method comprises identifying relevant peak sample data points associated with each of a plurality of detected peaks and determining a peak shift amplitude associated with each of the detected peaks using the identified relevant peak sample data points. The method further comprises comparing the peak shift amplitudes associated with the detected peak to a peak shift test level and incrementing a counter each time the peak shift amplitudes associated with the detected peaks exceed the peak shift test level. The value associated with the counter relates to an amount of peak shift margin associated with the digital peak detector.
