Hi,
here is some info about the first part of my homework, for those, who want
to break down their signal (heart beat or whatever) into a collection of pure
sin waves to analyse main frequency magnitudes and phases.
First some very un-mathematical applied theory:
If you sample a waveform

Wolfgang,
I've used R's fft to filter ECG signals and will comment on your
commentary based on my experience. First, as an easily
accessible reference, I suggest The Scientist and

i.e. I have a heartbeat signal and would like to decompose it into pure sin
waves, getting three vectors, one containing the frequencies of the sin
waves, one the magnitudes and one the phases (that's what I get
