Talk:Signal generator

message: I added a sentence on and link to synthesizers. I think it's important to link to this page
as it contains information about the generation of waves that mightn't be found otherwise.
I first came to this page looking for a program that could generator arbitrary waveforms, and more generally
to find out about creating arbitrary waveforms on a computer, but couldn't find the appropriate 
information (much of which was contained inside the synthesizer page). I wouldn't have thought to
look at the synthesizer page for this sort of information, as it seems to refer more to instruments,
and this page seemed more appropriate for what I was looking for.
The 'or slightly more intricate methods' refers to the more complicated methods of waveform generatorion used by synthesizers,
and is intended to say that the synthesiser page tells you about these. Thus one might like to
add synthesizers as a 'See also' if they change this phrasing, but I didn't want to do this
because it went against the ordering of the rest of the article.
I know information about synthesisers was removed before, but I feel a link is necessary.

message: "The mathematical description of an oscillator involves a description of a continuous function that varies cyclically above and below a mean or other reference, extending from -infinity to +infinity, never fading, never diverging. This can be represented as a series:
"For example the series 1, -1, 1, -1, 1, -1,... is an oscillation"
The fact that the author of these words uses the word "series" incorrectly when "sequence" should have been used probably explains why I have problems with the earlier parts of the first paragraph quoted above.  What does "varies cyclically" mean?  Does it mean "varies periodically", so that, for example, Besocovich's "almost periodic functions" would be excluded?  What does "extending from -infinity to infinity" mean?  My first guess was that it meant the domain is the whole real line, but that would exclude the sequence that the author incorrectly calls a "series".  My next guess is that it means the domain is a subset of the real line that has neither an upper bound nor a lower bound.  But why doesn't the author say so, instead of phrasing it in a way that cannot be understood except by surmises based on his proposed example?  "Extending from -infinity to infinity" could be construed by reasonable readers as referring to the range rather than to the domain!  This is horribly sloppy writing, to say the least.  I will not try to correct it myself, since I don't know the conventions of this area.  -- Mike Hardy

Much of this material is duplicated under oscillation. I suggest:
*Rename most of (1) "Signal generator";
*Delete (2) as it is covered in oscillation; and
*Rename (3) "Oscillation (mathematics)" and hope somebody can sort it out. I agree with Michael Hardy that I don't really understand the intention here.

replies: text: Perhaps (3) could find a home under convergence which could do with some work in any case. Cutler 14:32, 18 Feb 2004 (UTC)

text: In fact (3) is covered more succinctly under periodic function so I suggest that it is deleted unless somebody wants to merge it there. Cutler 15:20, 18 Feb 2004 (UTC)

text: Proposal -
#Delete (2) as it's all covered in oscillation.
#Move (3) to a new page periodic function/temp and alert Talk:periodic function.
#Rename Oscillator > Signal generator
#Redirect oscillator > oscillation.

message: It has been suggested that this article be merged with Function generator.
I believe this would be a mistake. "Function generators" are a very specialized portion of the vastly-larger world of generic signal generators. Besides function generators, signal generators include such beasts as low distortion audio generators, noise generators, microwave generators, sweepers, synthesized signal generators, and so on.
I believe that the articles are correctly factored as they stand.

replies: text: This article isn't about signal generators, then, by your definition.  It's about function generators, and should be merged into function generator.  If you want to create an article about signal generators in general after the merge, feel free.  — Omegatron 17:23, 2 November 2005 (UTC)
thread_title:  Merge? 

message: I've rewritten much of the article, and added lots of information on other types of generators.  As a result, I've removed the  tag.
One paragraph that I didn't know what to do with was this one:
:In musical sound synthesis, oscillators conventionally form the most fundamental synthesis building block.  With analog synthesizers, they are realized with voltage-controlled oscillators and with digital or software synthesizers they are generated algorithmically.  Modern software synthesis environments such as Csound have generalized the oscillator as a type of unit generator (UG), where UGs are primitive modules that produce, modify or acquire audio or control signals.
This is interesting, but use of oscillators in applications besides test equipment is really irrelevant to this article.

replies: text: You are right to remove the information... It should go in some article about general electronic oscillators or synthesizers, not here. -- uberpenguin 03:02, 5 March 2006 (UTC)

message: The image under Special purpose signal generators shows a "toner probe" or "tone probe" used to trace wiring, but there does not appear to be any text explaining this usage outside the image caption. Should the article be expanded accordingly? --SoledadKabocha (talk) 19:03, 20 February 2016 (UTC)
