Hi there, I am a music student and have no math background whatsoever but was wondering if you guys could help me with something that I read in a book on signal processing. I want to create a periodic waveform that is described by the following fourier series http://dsp-bg.info/files/example_119.jpg. I would like to know how to figure out different values of f with f1 being the fundamental frequency, for example I want to be able to calculate the values for f1+ f2+ f3...+n ect. I have been given the amplitude values (An) of N=8 already but need the frequency components (f1 ect) in order to generate the waveform. I am pretty ignorant in this area so If I have not been clear in my question I apologise in advance. Hope someone can help. Thanks,B.
