摘要
Time-frequency distribution techniques viz., STFT, WVD and CWT were studied using simulated HRTS data. It is concluded that CWT showed better performance in time-frequency representation. This technique is extended to compute the real HRTS. It is observed from the CWT spectrum that more power is concentrated in low frequency region in MI patients and vice versa in case of normal subjects.
