How can I convolve 2 sets of data in Excel?
I want to apply windowing functions to the frequency domain data from Fourier
analysis. This involves convolution with the transformed window function. For a Hann(ing) window this has only 3 real components but the convolution needs to 'wrap around' at the extremes of the frequency domain. Has anyone solved this problem and has a set of coeficients for all the common window functions? |
