3.72 FAQ-309 How do I carry out deconvolution?

deconvolution-methods

Last Update: 2/3/2015

Deconvolution is widely used in many research fields, e.g. supramolecular chemistry, calculating fluorescence lifetime.etc. In Origin, there are several approaches to do deconvolution for different scenarios:

• The data is a convolution of Gauss and Exponential functions:

  Directly fit the data with the built-in GaussMod fitting function in the NLFit dialog.

• The data is a convolution of two functions (but not Gauss and Exponential):

  Follow the Fitting with Convolution of Two Functions tutorial.

• The IRF(instrument response function) is very complex and cannot be defined by a function:

  Follow the Fitting with Convolution tutorial.

• Use deconvolution to analyze peaks:

  Refer to this FAQ, or use FFT to do deconvolution.
