Spectral Analysis

Use AcqKnowledge to obtain the power spectrum of the EEG. The power spectrum indicates the power of each frequency component present in the source time domain waveform. Perform power spectral analysis on EEG data from different leads and overlap the results. The FFT in AcqKnowledge allows frequency representation using linear or logarithmic scaling.

  • Maximum
  • Minimum
  • Frequency

Use the automated analysis routine to divide the EEG signals into fixed-width time epochs. For each individual time epoch, the Power Spectral Density function of AcqKnowledge is used to estimate the power spectrum of that epoch using a Welch periodogram estimation method. From this PSD the following measures are extracted for each epoch: Mean Power, Median Frequency, Mean Frequency, Spectral Edge, Peak Frequency.
