text: In some cases, where you can model the shape of the signal accurately by means of a mathematical function (such as a polynomial or the weighted sum of a number of peak shape functions), the noise may be isolated by subtracting the model from the unsmoothed experimental signal, for example by looking at the residuals in least-squares curve fitting, as in this example.
