Quote:For the non-mathematicians out there, linearity is one of the prerequisites for Fourier analysis to be applicable.I'm not sure what you mean? First of all if a function is linear why would you model it - it's pretty easy to predict. Second of all, unless the linear function is horizontal (even easier to predict) you actually can't model it with a Fourier analysis since you need bounded variation (sines and cosines are periodic so they can't do this).
