#450905 — why analog electronics

FromJohn Larkin <jjlarkinxyxy@highlandtechnology.com>
Date2017-03-08 17:11 -0800
Subjectwhy analog electronics
Message-ID<jea1cc5ealcjf3b9ot1kfsuqkl0lu6me44@4ax.com>
The Brat is in the UC Berkeley MBA program, and one of her profs took
his entire class to dinner at Chez Panisse, which ran about $200 per.
He was asking about our company, and was surprised that anyone still
does analog electronics. "Isn't everything digital now?" He's not
being a jerk, he's seriously wondering why anything is analog.

So, I'm going to write him a little essay on "why analog?" Who knows,
maybe he'll take me to Chez Panisse.

"Analogue is the Future" - that's all anyone needs to know.

Except w.r.t. photon counting and femtoamp measurements.

If it only was so harmless!


St. Augustine, magister ecclesiae:

"The good Christian should beware the mathematician and all those who 
make empty prophecies. The danger already exists that the mathematicians 
have made a covenant with the devil to darken the spirit and to confine 
man in the bonds of hell."


regards, Gerhard

Godel might have said: "God made countably many provably undecidable

Ok he might not have called it "ZFC set theory" but whatevs.

Oh no! There we go again.

Perhaps not even there.

http://adsabs.harvard.edu/abs/2009PhRvA..79c3802B

I heard a lecture today from Prof. Robert W. Boyd on impressing an image from an orthogonal basis set onto a single photon, then distinguishing between the photons carrying the various possible encodings with a holographic matched filter.

He managed to transmit 2.1 bits worth of information per photon, and pointed out the theoretical information content was infinite. He used seven possible states to shift his 2.1 bits, and pointed out that it would have taken a much lower-noise set-up to do better. 

Not a result I'd have expected. The electromagnetic field corresponding to a single photon is a whole lot more complicated than I'd imagined.

Plank and Einstein pointed out that total energy of a single photon was fixed, but they didn't say anything about how it might be structured.

Neurons either fire or they don't - there's no analog in-between.

Yeah, but single ones rarely have any useful power; it's like a single 
poster yelling at The Internet.

That said, I imagine there are a few neurons with unusually high 
"responsibility" for certain tasks, like actions in the motor cortex.  That 
would be a reasonable explanation for why I sometimes get some random tic or 
twitch when I sleep wrong (usually oversleep, and usually a facial muscle 
like the eyelid or something).

Also, action potentials sometimes go off half-assed.  I don't know if that 
also half-asses the response that subsequent neurons have to the pulse, or 
if it only needs to exceed a modest threshold to be useful.  Anyway, there's 
some analog action in there, too; it's all just differential equations 
arising from chemical concentrations in solution.

Over a human time scale (fractional seconds, rather than milliseconds), it's 
only meaningful to average over the ensemble, in which case a trillion 
neurons ticking away looks reasonably continuous for hand-waving's sake.

I don't think neurons are that dumb. Even a single-cell critter can
have complex behavior; a neuron can too.

Could be that "firing" is a tiny part of what's going on. Firing may
not even be the main function of a neuron; it's just easy to observe.

Yeast cells don't fire, but they can make beer.

Oxidizing ethylene gas over a catalyst can't make beer, but it'll get you 
hammered.  And it's even dumber.

Ethanol exists in interstellar space, where we can be, well, somewhat 
certain that nothing is alive there.  (But it would be quite the interesting 
revelation, if the ethanol turned out to be, say, the spirituous emanation 
of a sentient being. *hic*)
