Assume that I have some generic antenna connector, followed by a pi-filter/50ohm impedance matching components, then a DC blocking cap (as per the RF switch recommendations) and then a RF switch fo...
I have been observing these little cases hanging to the wires from a long time. They are almost everywhere here in India, but I was unable to find out what they are. I am not sure whether they are...
This discussion was prompted by answers to this question. While the answers are good (basically, when designing for the medical field, either be or hire someone knowledgeable about the specific re...
I would like to save some costs with ideal diode controllers. Basic requirement is for the diode controller to block overcurrents (short circuits) in both directions. The MAX16141A IC can do it a...
Following a lot of discussion in comments, we're going to split this request: Capitalization changes: these were previously discussed and we'll make these changes for you. We can do this at t...
*Learning about EMG as a part of our research. My team has at least some experience with electronics that is worth mentioning, but don't have any experience with EMG/bio-potentials. Most EMG hardwa...
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'm not very familiar with this site but was pointed to it by a comment. That made me wonder, what exactly is the scope of this site when it comes to residential wiring? For example, Basic wiri...
Feel free to provide a list here and someone will go through and update them. For instance, I've just renamed [led] to [LED]. Please include both the old tag name, the new name, and ideally an expl...
Thanks for asking. In my view, if it's something you'd first think of asking an electrician, it's probably off topic here. That includes what type of cable to use, whether it should be in a condu...
67 tags deleted, 10 with posts still attached left alive.
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 am trying to figure out what is causing an Allegro A2982 source driver to burn up. The source driver (A2982) is connected to the coil of a Panasonic TXS2-9V relay. The source driver and coil ar...
Do common-source JFET amplifiers have an advantage over common-drain? The JFET would be in a low noise photodiode amplifier. The signal is 100us pulses with 10us raise times. Here are the schema...
Yes, votes on meta should not factor into rep. Meta downvotes indicate disagreement, not that you're a terrible person, have the IQ of a garden slug, and cast dispersions on your heritage like the...
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 ...
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...
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....
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...
Posts on Meta no longer affect reputation, per this discussion with a moderator on this question.
I was looking for guidelines of how to select appropriate cables for applications (I am interested in DC), I found IEC 183 standard which talks about high voltage cable selection for AC. Also, the ...
Starting with your first circuit: It seems a little klunky, but should work. I don't like the D1 and D2 diodes. The reason I placed D1 is to avoid triggering the mosfet with very low voltage li...
Is there a scientific way to estimate the resistance of a pogo pin? Ultimately there must be, but it generally requires knowing things you don't know. Worrying about the resistance of the barrel ...
When should a transformer core be potted? Whenever you need some of Mechanical ruggedness. High dielectric strength. Minimize vibrations (and therefore audible whine) from capacitive, inductive...
