# Comparison to Other Transforms ## Spectrogram The Stockwell transform retains both broad-scale and fine-scale structure, compared to a spectrogram, whose frequency resolution is is limited by the moving window size chosen. ![waveform](data/RJOB_EHZ_wave.png "waveform") **Spectrogram** ![spectrogram](data/spectrogram.png "spectrogram") ## Morlet Transform Wavelet transforms like the Morlet transform, for example, also do this, but the y-dimension of the 'scalogram' is not frequency, it is "scale". ![Morlet comparison](data/morlet_comparison.png "Morlet comparision")
