Hello! Does a package exist in Julia which takes a signal and return the Fourier Coefficients needed to approximate this signal? Kind regards

@Geoffrey , I have edited your code below to be closer to the definition of the Fourier coefficients, used the standard fft and adjusted the length of input signal x to contain N samples. The minus sign required in the imaginary part of the fft, is probably due to the fft sign convention in Julia. E…

@Ahmed_Salih the ak and bk coefficient from my code should be what your are looking for… just need to figure out why the reconstruction need to be inverted and shifted !
