Once you have calculated all the desired terms of the Fourier series at each sample point, you need to find the (truncated) series expansion of the function at each of those points. This corresponds to adding up all the calculated terms at each point. The summation can be performed easily in EXCEL by using the build-in function SUM(). how to lose the last 5 kgs Finding Fourier coefficients for square wave. Fourier series.

- I rarely find the two-sided Fourier transform useful, and instead plot the one-sided Fourier transform as described in this documentation for the fft (link) function. All good signal processing textbooks (for both discrete and continuous signal processing and filter design) discuss discrete and continuous Fourier transforms in detail.
