[English] Antonym of Analog Front End
« on: December 29, 2017, 08:49:03 am »
Circuit for conditioning signal before ADC is called AFE, what is it called if a collection of circuitry is used to post-process DAC signals (IVC, LPF, PGA, etc.)? A search on Google for analog back end doesn't result much useful information, so I wonder what is it called.

The proper term will depend on what you wish to communicate. The reconstruction filter is mandatory, hence its
"special" name instead of "low pass filter". The rest of the elements can be necessary or not, depending on your needs.

In case you don't want to deal just with the mandatory function I also vote for "output stage"-

In portuguese I have used the term "analog rear end" to generically define the analog circuitry at the system's rear end stage. However, this may not be quite true in english, thus I suspect "output stage" may be more usual.

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

Analog Back End?

The maddening thing about English is it's logical, *if and only if* you have a comprehensive understanding of every human language. the English borrowed from everything and Americans have continued the practice.

Since the audio DAC's used to be all current out, I used to use the basic term 'IV stage' to represent everything, current to voltage amp and sin(x)/x filtering and reconstruction and analog line driver.  Or, output buffer.

Since you are dealing with audio, maybe you should ask as 'diyaudio' in this sub-forum:
http://www.diyaudio.com/forums/digital-line-level/

They are better suited for the term you may be looking for rather than us specific technical engineering guys...

Actually they have some very technically knowledgeable people there. Check out this Dutch gentleman, MarcelvdG here:

Ok, you kinda missed my meaning.  I meant to say you are looking to access knowledge from those with the type of 'terminology' to sell a premium audio device which many of us here (not necessarily me) which you need to use to get the high $ which your design deserves.  I assume part of what you are looking for is also how to market to the high $ crowd.

The audiofool crowd will have heard of an "analog front end", so calling it an "analog back end" will be sufficiently intelligible to them.  Then add some BS about reconstruction accuracy, etc.  "Digital Processing Analog Back End" should be plenty of smoke and mirrors once marketing describes its virtues.

How about "analog reconstruction engine"?

It is actually a correct functional description, without committing yourself to anything definite, and it sounds good  ;D

DBS - Digital Back Start. Perfect antonym, and confusering enough to audiophools, it just confused me. :palm:

Ok, a term you can use which no one else is using + a good marketing and brochure text for a premium audio device which you can trustfully say it's true, and no one else is using the term.  Though, your output filter better have at least 1 inductor in series in it to be true...

Gaussian Analog Filter
or
Gaussian Analog Interpreter
or
Gaussian Analog Interpreting Filter
or
Gaussian Analog Reconstruction Filter

You can exclusively use this term to separate you from everyone else.
