Why are CY capacitors on the source side, and not on the load side? You may not be grasping what the image shows. The left-side port connects to the AC power-line. It supplies power to the rig...
There is no "standard". Do whatever works best for the situation at hand. In a microcontroller, it's usually easier to measure period than frequency, especially for "low" frequencies like the pow...
For easy reference and to protect against possible edits to the question, here is the circuit you are asking about: In order to attenuate a signal, you need two impedances. Imagine you had a 0 ...
A circuit under question: Why are CY capacitors on the source side, and not on the load side? Henry Ott describes this with: “Because filter attenuation is a function of impedance mismatch, th...
If you're talking oscilloscopes, I used to do peak-to-peak measurements for the time period. And then, as you note, invert for the frequency.
In a general sinewave as below, is there a "right" way/"standardized" way to measure line frequency - and how do energy meters calculate that? measuring pulse width of half-period, ie. time elap...
There is no provision in FatFS or the fat32 filesystem in general regarding hot-unplug, so this behaviour depends wholly on the implementation layer for your hardware. As an example, in my use cas...
Consider a device with a microSD card. The microcontroller writes to the SD card periodically. The operators have an ability to remove the microSD card at any time (they will be removing it every...
The flashing-light frequency shall be 90+/-30 times per minute. I don't know what could be more clear. This spec says that the light must flash 90 times per minute, ±30 times per minute. In othe...
I was analyzing the design a hazard warning light.The spec of the light turn on off is given below. The flashing-light frequency shall be 90+/-30 times per minute. May I know in this case the...
Your question is ambiguous. First, you need to define "rise time". That applies to a step, not a periodic signal. Let's say you have a 0 to 5 V digital signal. The rise time is how long it take...
May I know how to calculate a signals rise time from it's frequency. I found this article for the same. The formula given is Tr = 1/f*π. May I know is this applicable for PWM also.
Every real part has resistance including your piezo current source. Every switch resistance is a loss in energy (I^2 R * t)=E and includes diode and transistor switches. What you need, I think, is...
I'll take it that you want this circuit to actually work, not just appear to work in some software simulation. In that case, it's about the circuit, not the simulator. A simulator is just one too...
I'm working on an energy harvesting circuit known as an in-house harvesting circuit (cc-ih) and would appreciate some guidance on implementing it in Simscape within Simulink. Circuit Description: ...
Mini-circuits LNA PHA-LN13+ has suggested: Eval board Layout Eval Gerber The image took from the Gerber file (3rd ref.) (Though all 3-reference mentioned containing it): There I have som...
The black one is a tantalum capacitor. There are various weird ways to mark these (because typing out 100u instead of 100- would be too easy...). If I'm correct in this case, I believe: 100 stan...
The component with the coil of wire is an inductor. Judging from the small size, it is probably only a few µH. There are lots of uses for inductors, like for filters, switching power supplies, tu...
I have here an acre-counter or crop counter device like the lykketronic shown below, using two AA batteries. It arrived without working. Upon opening its case, I found that the PCB is missing tw...
First, common mode is something that only applies to a differential signal. When a signal is encoded in the difference between two voltages, the common mode voltage is the average of the two. The...
I am currently learning amplifier design, after constructing the unity gain amplifier(which is a differential-input single-ended-output amplifier) in the unity-gain feedback configuration I have pe...
Question about relative humidity specification for electronics. Industrial automation, indoors, cabinet or instrument enclosure. The failure mechanisms at the upper limit are fairly intuitive. I'm...
That circuit is drawn rather obfuscated, but it does seem to make sense: Start by looking only at D1, D2, C1, and C2. Pretend D3, C3, and D6 don't exist. Although not drawn very well, this is ...
I am working with an IC that uses a partially intergrated regulated charge pump. The circuit looks like this: It behaves like a voltage doubler. However, when looking at other regulated charge p...
It's really not clear what exactly happened in that video. We see someone slinging a hook over the power line, then we see a white picture. We don't know what the cable was made of and where the ...
