[R] average waveform over many cycles

[Moshe Olshansky]

Hi Bill,

You get cyclelemgth = 110.
If this is true, i.e if every 110 points of data
represent an entire cycle then everything is all
right, but are you sure this is true? Think what
happens if the true cycle length was 110.5 data
points.

Regards,

Moshe.
