 Title: Anyone can help with Fourier synthesis? Post by: Alliance on November 05, 2005, 09:04:42 am Anyone can help with Fourier synthesis?Our tutor gave us this exercise and i have no idea how to do it!!!Plsss help someone.....Link belowhttp://img382.imageshack.us/img382/7835/scan0015ks.jpg Title: topic298 Post by: Fu-Kwun Hwang on November 05, 2005, 12:58:16 pm The question is how many harmonic do you need?So you can plot the function with 2, 3, 4, ... and see how many harmonic will give you a reasonable approximation. You need to decide what is a good approximation first.
