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 ...
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 ...
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 ...
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 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...
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 there are a lot of tags referring to general physical quantities (e.g. current, voltage, frequency) I'm not sure if they are useful. For example, what usage would have the tag voltage...
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 ...
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...
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'm in the process of giving the tags page some structure, writing tag descriptions and creating synonyms and some hierarchy. I'd like to know the Community stance on a new tag I'd like to add: b...
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 ...
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 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...
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....
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...
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...
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...
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...
Since my question didn't get an answer yet, I post this answer as a possible solution. What I'll describe is not meant to be the right way to port an answer from SE network, but just a possible ri...
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...
