Re: LF: LF EbNaut test from JN80 on 137370

Hmm... the old problem with "I leading Q" or "Q leading I" if the signal 
frequency in the complex stream is positive.
When loading Andy's file in a curve editor, I see the 2nd channel leads 
the 1st by 90 degrees.
"positive or negative frequency" per definition ?

Cheers,
