Hi everyone,

How can I perform deconvolution in the frequency domain by dividing the spectra of the numerator by the spectra of the denominator?

Best regards, Maria.

The standard technique is called water level deconvolution. The top three hits in a Google search on the words

For his deconvolution he used a water-level stabilization method and a .... SAC files and the IO parameters (filename, water level, Gaussian width factor, etc., see ...

If a waterlevel is not set by the user then a waterlevel of 1.0e-04 will be used in the deconvolution. In the output SAC file, the component name is changed by ...
