Re: [time-nuts] Flicker Noise Reduction

[ed breya]

That's pretty slick. I think I see what's going on in there. It reminds 
me somewhat of optical chopping, but in this case, it looks like it's 
not about the 1/f LF/DC offsets adding to the amplitude, rather their 
effect on gain that's important. It seems to me that if the the gains 
are predictably correlated with the 1/f noise in the stages, then 
another approach may be to look at the actual 1/f noise (of the bias 
levels, not the THz signal) of the amplifier stages, and process it to 
provide continuous gain compensation, without a sampling system.
