From: Optimization of Weighting Factors for Multiple Window Spectrogram of Event-Related Potentials
Logarithmic spectrogram of SSVEP of short-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) 9 Hz, 10.4–12.2 s, (d), (e), (f) 9 Hz, 4.7–5.7 s.
