Time-frequency analysis of visual evoked potentials using chirplet transform
Jie Cui, Willy Wong, Steve Mann · Electronics Letters · 2005
Chirplet time-frequency representation has been applied to characterise visual evoked potentials (VEPs) successfully. The approach presented here can represent both transient VEPs and steady-state VEPs clearly. Comparison to the method of short-time Fourier transform (STFT) is reported.
