Time-Frequency Wavelet Family and its Application in Electrograstrographic Signal Analysis
Xiang Xie, Hun Hsuan Sun · 1998
This paper wavelet family, with bo:h oscillating patterns, of a regular time-frequency analysis for wavelet trar both stationary and convenient trade-off frequency and frequency given time-frequency window functions are frequency wavelet family real sine wavelets and using these four windc condition. The tim corresponding wavelet has also been investigated. cosine window sinusoid time-frequency resolution. modulated Gaussian Gaussian window complex describe our sinusoidal time-frequency analysj signals to simultaneouly activities and track low introduces a sinusoidal time-frequency real sine and complex exponential \.arious window functions. It provides analysis rather than a time-scale sform time-frequency localization of lion-stationary signals. It offers a between time resolution at low resolution at high frequency for any analysis application. Four different studied for the sinusoidal time- and it has been shown that both the the complex exponential wavelets ws satisfy the wavelet admissibility e-frequency resolution of the time-frequency localization analysis It has been show that the rising- a1 wavelet provides close to optimal It has also been shown that the w:.velet becomes a special case of the exponential wavelet. We briefly wavelet family and apply it to the s of electrogastrographic (EGG) localize high frequency spike Sequency slow waves.
