Raw Measurements

     This group of variables stores all the measurements that are taken directly from the signal (except CCA and MouseLog). All the quantities contained in Summary Data are derived from Raw Data.


Figure 1 - Descriptive measurements obtained by Sound Ruler. The oscillogram illustrates nine points of amplitude measurements (red dots) which delimit eight energy ranges. The spectrogram shows the dominant frequency being tracked with frequency and amplitude at that frequency measured at the nine amplitude points. In addition, it shows amplitude measurements at the frequencies of the harmonics chosen by the user. The power spectrum illustrates tuning, by emphasizing the width of the peak at half and one tenth of its amplitude.

DomFreq_10_End Dominant Hz at final 10% peak amplitude
DomFreq_0_End Dominant Hz at final 0% peak amplitude
Q-3 Frequency tuning Q-3 dB at the pulse peak
Q-10 Frequency tuning Q-10 dB at the pulse peak
Ampl_H1 Amplitude of harmonic 1
