Are there any programs for the HP-48SX that computer Fourier series coefficients or Fourier transforms? Any programs or information would be appreciated. Thanks in advance! -- Brian S. Schang N8FOG brian@fog.ann-arbor.mi.us 46131 Academy Drive schang@caen.engin.umich.edu Plymouth, MI 48170-3519

Brian,
I wrote a simple, short program about 7 months ago to compute Fourier
coefficients, and then, after specifying an upper bound for the summation,
I had it re-plot in the standard (sin,cos) realm. The biggest problem I
encountered was the time used by the HP to determine the coefficients.
I found that for some of the more complex functions, I was better off
determining the coefficents by hand, as for the plotting, I always leave
that to the HP!
