%And added, "he *may* have meant a 180 deg phase shift for each of the
%frequencies that add up to his composite signal.  The output signal will
%definitely NOT look much like the input signal.  You can prove this to your
%self ..."

Yeah, that was me.  Ever have one of those days?  I actually *did* write
this out, but of course, I did it wrong.  The mistake I made was overthinking
the problem and working on it for non-multiples of 180 degrees also.

But back to your original comment.  I've never looked at the first replies
to USENET questions and said, "That's the definitive answer."  I always
wait a few days.  Usually, the first ones in (like me in your example)
haven't thought about the answer completely.

USENET provides expertise through consensus.  I consider the discussions
(even in this group) more or less like bullshit sessions with coworkers
and friends.  We eventually get around to the right answer.

[Re:  Lack of "I think" prefacing my statements.  "I think" on USENET,
 it goes without saying that what you write is what you think.]
