    Fourier transform techniques 1 The Fourier transform Recall for a function f(x) : [ L;L] !C, we have the orthogonal expansion 2 Solutions of differential equations using transforms Here we give a few preliminary examples of the use of Fourier transforms for differential equa-tions involving a function of only one variable. Going back to the example where we transform an image by taking brightness values from pixels, those pixel values are never continuous to begin with. (Remember that the Fourier transform we talked about in previous section was about a continuous function .) Our mathematicians came up with a good solution for this, namely the discrete Fourier
