#Narrowband Filtering

The wavelet transform can be used to isolate localized bands of variability, such as those due to tides or internal waves.

To do this, we note that the wavelet transform at a particular scale `$s_o$`, or equivalently a particular frequency `$\omega_o=s_o/\omega_{\beta,\gamma}$`, is simply a *one-sided* (or a
