I'll bet _anyone_ who has had the experience would. :-)

Damn, why was that the first thing I thought of as well...

I've always found the demodulation of a DMT signal
impossible. If you know what I mean, shame on you. :-)
Sorry, that's an in joke for some who have had a certain
illicit experience.

Morten,
I don't know what DMT is, but signal inversion shouldn't be a problem
for demodulation and can't be fatal. You can also invert a sign in software.

Hi all,
Ive come to another promblem with the project I'm doing on DSL. I can't seem
to figure out if a 180 degree phase reversal (hardware inversion) will make
the demodulation of the DMT signal impossible.
As I see it there will be a problem with phaseshifts that holds the carrier
waveform "positive" for more than a half period, like the QAM modulation on
the picture.

But how will it affect the DMT ?
Thanks in advance
