I have been using a continuous 1-D wavelet transform (MATLAB cwt function) to compute and plot wavelet scalograms. For my research, I need to know the time and frequency resolution of the scalograms, but I could not find this information from any of the MATLAB documentations I looked in...
Longer segments provide better frequency resolution; shorter segments provide better time resolution. The segment lengths can be controlled using the FrequencyResolution and TimeResolution parameters. When no frequency resolution or time resolution values are specified, pspectrum attempts to find a good ...
we introduce a spectral estimator enabling time-frequency super-resolution, called superlet, that uses sets of wavelets with increasingly constrained bandwidth. These are combined geometrically in order to maintain the good temporal resolution of single wavelets and gain frequency resolution in upper ban...
By incorporating the wavelet analysis into the FTP task, a time-frequency perspective is provided to perform the pattern recognition for different time and frequency scales, making it highly effective for multi-resolution analysis to enhance the FTP performance. In addition, the proposed approach also...

You would have poorer frequency resolution without gaining any time resolution. But that is quite often not the case. The human auditory system works this way; we have much better frequency localization at lower frequencies, and better time localization at high frequencies. Plot the scalogram of ...

The frequency resolution is the minimum frequency interval that can be distinguished by certain algorithm. 频率分辨率是指所采用的算法能够被识别的两个单音信号的最小频率间隔,在实际测量中,通常根据频率分辨率确定所需要的最小采样点数。 3. The frequency resolution and the character of real-time are also...
