I wanted to look at how the power out of a clipper varied with the
applied signal level. This is not rocket science, but my search for a
canned solution came up dry. I ended up building a spreadsheet using
numeric integration to calculate the Fourier Series coefficients. I
have posted to the files area some results (for n=1, n=3, and n=5)
normalized to a clipping level of 1 volt. See "Clipped Sine Wave.XLS"
if you have interest.

One detail: it is not necessary to integrate for calculating Fourier
coeffficients. There is a method based on jumps of the function where you
have only to sum finite things. Any good calculus book will show you.
