I'm designing remote controller based on NRF24L01 and STM32. I want to use SMA antenna. My question is regarding power amplifier (PA). When is it necessary to use one? The range I'm aiming for is 2...
I agree that the particular question was correctly closed. Questions about protocol stacks aren't necessarily off topic. However, this one was because nothing about it had anything to do with ele...
Hello I don't understand how this differential to single-ended voltage converter can work. What I don't understand is why we place a current mirror(a current mirror copies the current flowing thr...
Here is another "functional explanation" of this phenomenon (see also my RG question). General feature. Unlike resistors that directly decrease current, both capacitors and inductors do it by subt...
What you describe is already allowed in Papers. See electrical.codidact.com/help/papers. The papers by Circuit Fantasist are well on topic. Presenting a concept in an accessible way is OK. I ha...
I was reading through the datasheet of a boost converter, TPS61023 from TI. In the "Input Capacitor Selection section", they give the following advice: 8.2.2.5 Input Capacitor Selection Multil...
The TESATRONIC TTD20 is a precision length measuring instrument used in various industrial and laboratory settings. On the backside it provides a 15 pin interface for reading out signals: I want...
I'm trying to implement a circuit I read about in a book recently, but having a hard time deriving the relationships for the required impedances for error corrector balance. Here is the circuit: ...
My circuit includes the following components: • PIC16 with internal clock, frequency: 32 MHz • ST LED2000 LED driver (a buck converter) with a PWM dimming input. The converter itself isn't a conc...
I am learning IC design layouts using Cadence Virtuoso and now I got stuck with the concept of using vias. The question is when and where to use it? I am attaching the schematic of my inverter tuto...
Nowadays, that I videoconference over WiFi a lot, I've started to notice some trends in WiFi quality. And it seems my connectivity decreases when my microwave oven is on (I work in the same room a...
One of the aggrevations Elsewhere were all the vandal and retribution downvotes. They never took the problem seriously. Now it's happening here. Andy was the latest target, twice, recently. I'v...
We have such low volume as it is, that I wouldn't want to see another category added at this time. It would only emphasize how little traffic there is. Let's not make the same mistake that Photog...
We haven't really addressed what SE would call "requests for external resources" here. I think it's quite clear that we aren't taking shopping recommendations, as in "where do I buy this part". Ask...
How about this: I create a meta thread here where everyone is welcome to post contents, feedback and proposed changes. The question of the meta thread should contain a continuously updated draf...
This can be OK if you consider and address the consequences carefully. It's something I would only do as a last resort. Usually I try to make sure the hole itself is outside the outline of the pa...
A while ago I made a question about the monostable multivibrator .Lets get a picture of it: When switch is closed it enters its unstable state and it eventually returns to the stable state Howe...
I agree that "208VAC" and "230VAC" are too specific to be useful. I tried to edit the post to remove them. There is apparently a bug in the system. While I removed both tags from the post, one o...
Assume we have a channel and send 7-bit data(0100100) asynchronously with 1 parity bit(0).Suppose the start bit is 1.The end bits are in the same logic level with the idle state of the channel(0).H...
How does the receiver understand the end bits? It doesn't. The purpose of stop bits (what you seem to be calling "end bits") is to leave a guaranteed gap before the next start bit. The leading e...
Is C2 here to protect the voltage source from thermal noise? There's absolutely no chance that any level of thermal noise produced by a resistor will be sufficient to cause any reasonably desi...
We use a DC externally excited generator/motor as a generator.We excite the input of the generator and get at the output 10V at 1Wb flux and at 5rps generator speed without connecting the generator...
