[sdiy] Request brain dump on balanced lines -- harmonic numbering

[Scott Gravenhorst]

What is the official correct way to number harmonics?

Is the fundamental considered the first?  Or is the
fundamental not considered a harmonic at all?  To my way of
thinking, which may be completely in error, the first
harmonic is a sine wave one octave above (or 2x the freq) of
the fundamental sine wave.  ??
