[LAD] Converting single-cycle wave to harmonic spectrum

[Jeanette C.]

Hey hey,
I'm trying to convert a single cycle wave to a harmonic spectrum. I know that 
in theory this is a job for standard FFT. I wondered if there isn't a 
"simpler" way given a few assumptions about the input.

The input waveform is exactly one single cycle
The waveform has only harmonic overtones.
That means that only integral multiples of the base frequency need to be 
considered and the specific Nyquist frequency is determined by the number of 
samples (I think).

I treid searching, but it appears that I don't have the right keyword to hand, 
getting only very general results bordering on the off-topic. :)

Can anyone help? A good keyword, name of an algorithm or a general name for 
this specific task would be helpful enough, I suppose.

Best wishes,

Jeanette
