Re: "hi Tom, thanks for the clarification on phase, absolute phase, and all those other phase things."To clarify, you did not err in your vocabulary. The term "phase" is applied widely to both matter of phase and matters of polarity. I was trying to clarify that there are various related happenings, which would be better served by using two different terms: Polarity to refer to the direction of the signal and Phase to refer to the inner relationships of various elements of the signal. The term Absolute Phase is often substituted for Polarity, which would be the more precise term.
