Deconvolution issue #33

Open davidfee5 opened 1 year ago

davidfee5 commented 1 year ago

I noticed an issue with spectral deconvolution recently and think we should maybe add a water_level value when we remove the full frequency response. See attached couple figures where some higher frequencies seem to get amplified when we do not account for a water_level. This could perhaps also be fixed by adjusting the pre_filt.

Interesting example. I'm used to things blowing up in the low end rather than the high end!
