Your title question about the "Gaussianity" brings up a lot of thorny issues, since noise in electronic components is quite a difficult topic from a physical, fundamental point of view. TL;DR: Fr...
I'm too new to this site's mechanics to judge whether a new category is warranted or not. However I really welcome the idea of supporting design reviews (both HW and SW) to a larger extent than si...
A definitive answer is hard to give, since the information is not easily available. However, after a bit of research I'm inclined to believe that the most common materials are copper, copper alloys...
Something that hasn't been mentioned in other posts yet is that ESD events needn't be utterly destructive. Most ESD events are "microevents". That is, they don't damage a part by rendering it non-o...
As the title says, I'm interested in a simple technique to measure the characteristic impedance of a cable using only the instruments available in a school lab or to a (somewhat advanced) hobbyist....
Sorry, but I have to challenge your premises when you say that most numbers are "round numbers" and that could be a reason for choosing some value. You compare those values by the number of decima...
I've noticed that in the edit account section there is a (inactive) link to one's content on a StackExchange site. This made me wonder if it is appropriate to transfer some content from EE.SE manu...
Although I joined Codidact from the beginning, I was never truly active and lost track of the development of the system and this site in particular. I've read the help and the "paper" category loo...
I just submitted a proposal to DuckDuckGo here for a new "bang" for their search syntax. If approved: !coddee search_term will trigger the following URL: https://electrical.codidact.com/posts/se...
Those are fiber optic cables that are wound back and forth between those "snowshoe" devices, which are used to limit the bend radius of the fiber. Those are needed to avoid propagation losses due ...
I've just finished a first clean-up of the tags pages, where I consolidated tags, provided synonyms, wrote guidance text and defined some hierarchy. As a result there are quite a lot of "dead" tag...
I've done a lot of work on tags lately and I'd like to share with the community some thoughts about the way tags should be named so that maybe it could become part of the FAQ and so hopefully lead ...
Here is another take at that problem. First let's define some quantities that will be useful later: \[ \begin{align} A &= \frac {V_2} {V_1} \qquad\qquad B = \frac {R_L} {R_S} ...
I agree with the answer of Lundin except for point 3 disambiguation. Regarding 3), in case a term does have several different meanings and all meanings are on-topic, then the most common/jangon ...
I don't have that book, but the statement you cite (emphasis mine): ... when s=jω the integral on the RHS of eq. 2.48 does not converge for unstable systems doesn't mean the transfer function...
What is the concept behind the dynamic resistance that often pops up when dealing with non-linear components and the circuits in which they are employed? Is the concept related to other terms like...
I largely agree with Olin Lathrop's answer. However, I think questions should be on-topic also if the trends have no direct technical motivations, on condition that the reasons can be backed by ha...
Introduction Yes, all those terms denote the same concept, that of differential (or incremental, or dynamic) parameter of a device. In the following I will explain such a concept initially in the...
RG58 cables come in different variations, even with Teflon dielectric suitable for 200°C operations. Your cable, being suitable for up to 80°C, seems to be one of those with a PVC jacket and Polyet...
One of the main reasons was hinted by Olin's answer, at the end, when he spoke about non-linearities. The same is hinted in the excerpt in Nick Alexeev's answer ("they would overload the player amp...
Most of the issues have been discussed by other answers. However I would like to clarify something about pure water (a.k.a. "distilled water" or "demineralized water"), which is "apparently" not a ...
I think we should definitely allow technical terms translations, because it's really difficult to find reliable sources online. And the translation process can be tricky, since the translated term ...
I agree with Olin and Mu3 answers. I'll add that you should aim not for just one kind of "high level" component, but many more basic ones. Not every EE course is the same across the world, and man...
I know that many JFETs parameters have a very large manufacturing spread, in particular, $I_{DSS}$ and $V_{GS(off)}$, as one can see (for example) in this datasheet excerpt: ... My question i...
In my effort to clean-up and organize tags on EE.CD I arrived at a point where there are a lot of old tags with wrong capitalization. How should I request the staff to change them? Should I post ...
