Power of signal and KTE

I have a spectrum that is a relationship between wavelengths and diffuse reflectance. Can I apply bandpower function and Kaiser-Teager energy at it?

The bandpower function calculates the average power of a signal within a specified frequency range.

Refer to the following documentation to learn more about the bandpower function:

Ensure that your data is preprocessed correctly. This includes converting your wavelength data into a form that can be interpreted as a frequency range and using the diffuse reflectance as the amplitude of the signal to apply the function on the spectrum.

The Kaiser-Teager energy operator is used to estimate the instantaneous energy of a signal. For spectral data, you can apply it to the reflectance values to assess the "energy" or "intensity" variation across wavelengths.

Note: The interpretation of results from these methods in the context of your spectral data might differ from typical time-series applications. Consider the physical meaning of "power" and "energy" in your specific application.
