From: Optimization of Weighting Factors for Multiple Window Spectrogram of Event-Related Potentials
Logarithmic spectrogram of SSVEP of long-event nonstationary character, estimated using a single window spectrogram with a Hanning window and the Peak-Matched multiple windows with EQWEI/SCWEI and with OPTWEI from Figure 5(b). Horizontal and vertical lines indicate flickering light of (a), (b), (c) 12 Hz, 5–10 s, (d), (e),(f) 15 Hz, 5–10 s.
