Abstract :
Rabbits were narcotized and stimulated by 0.5 Hz electric pulse. Potential of scalp was sampled at 3764 Hz. Wave components of rabbit somatosensory evoked potential (SEP) can be located precisely through the method of continuous wavelet transform (CWT). Frequency feature of SEP can also be analyzed by CWT. The technique of continuous wavelet transform, which can project a one-dimension signal into a two-dimension time-frequency space, will become a useful method to process medical electronic signal
