Has anyone else noticed a loss of reputation recently. I thought I checked yesterday and my reputation was a hundred points higher at 1889. Now it is at 1789. My vote summary doesn't indicate a los...
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...
Yet another example. If using MOSFETs only for power switching applications, it can seem like these are "robust" and "immune" to ESD events. While the package clearly states "ESD sensitive", devi...
I understand that white noise is not always Gaussian. In general, is the $V_{pp}$ and $V_{RMS}$ noise stated in operational amplifier and ADC datasheets Gaussian? And is its mean zero? Any exemptio...
One of the challenges with this particular controller is that it's wireless. Wireless devices need a) a clear enough RF channel to the receiver and b) a suitable power supply, namely batteries. B...
Many ESD problems are "latent" that is they do not sofort show up....some time later things will stop working :)
I know of a designer that didn't add ESD protection on a mass manufactured product in the field. They had to replace almost 10 thousand units, because they kept popping in certain low humidity and ...
I have seen multiple sources on the web discussing what they call concentric twist harnesses. It boils down to having a wiring harness built in layers, where each layer is twisted around the previo...
What you basically ask for can be done (I've done it), but not all your specific constraints can be reasonably met. The way to measure transmission line impedance is to drive a step onto the trans...
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'll let someone else answer about the device physics. I'll answer from an electrical engineering standpoint. The answer is: Maybe, but it doesn't matter since you should be considering worst cas...
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...
is the "X" point floating when there is no 12V applied ? Perhaps over a limited range, depending on whether the 12V line is left open or connected to something other than 12V. Case 1: The volt...
