摘要：
This paper presents a modified Continuous Wavelet Transform (CWT) for localisation of phase spectrum. The proposed transform provides us a frequency dependent resolution while maintaining a relationship with the Windowed Fourier Transform (WFT) and Continuous Wavelet Transform (CWT). A localized scalable spline window is used for dilation and translation while keeping modulating sinusoids fixed along the time axis. these distinctive features are absent in both WFT and CWT.
