Detailed Description

Module to detect peaks in window alternative to MBCountPulses.

Author

Marco Vignati

This module search for peaks in a waveform. It searchs for all positive derivative maxima above a given threshold, excactly as MBCountPulses does. The difference with MBCountPulses is that it alse searches for maxima in the waveform subsampled by a given factor. This is useful to detect peaks that are slower than the noise fluctuation.

• Config example:

     module PeakDetector
     verbosity = info
     enable = true
     ThresholdNumberOfSigma = 5
     endmod
     

• Parameters
  • ThresholdNumberOfSigma [double = 5]: threshold for peak detection on the derivative in rms of the derivative
• Optional Parameters
  • PulseLabel [string = DAQ@Pulse]: Label of the QPulse to be read
  • SubSampling [int = 5]: SubSampling factor for secondary search
• Reads:
  • PulseLabel (QPulse)
  • DAQ@PulseInfo (QPulseInfo)
• Writes
  • NumberOfPeaks (QInt)
  • PeakPositions (QStdVector<int>)
