Here are some ideas and relevant factors about the platform. I'm not expressing an opinion and am not voting (not being a core EE member), just offering suggestions about what is feasible. As alr...
WiFi or cell phone signals are way too fast for you to hear individual dits and dahs, and they don't use that kind of encoding anyway. What you are hearing is the carrier from a local ham radio op...
If I’m understanding correctly, most cable manufacturers supply two capacitance values in their cable spec (if you’re lucky). Those two values are: Conductor-to-Conductor (C-C) Conductor-to-Othe...
I've found a solution, and tested it. What @Olin wrote earlier holds. This is to post my code for STM32. Does the VBUS detection have to be done in an interrupt? I've asked the ST's technic...
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'm having trouble using the nodal equations to determine the base voltage Vb1 in the circuit below. I've attempted to write seven equations below, but not able to fit them in entirely. (12-Vx)...
For my own understanding I tried modelling switching off an inductive load without a freewheeling diode to observe ringing. This is the model I used: 1.) Are the two main components of the reson...
I benchtested below 0.7A constant current source circuit and observed few cycles of oscillation on drain current. With the help of bode plot analysis , I have managed to reduce the oscillations on ...
are there more elements contributing to this effect that I have not placed in the circuit? Definitely, but it's hard to say how relevant they would be. The real world is messy. There is parasiti...
What should the firmware do when it detects that VBUS (re)appeared? What should the firmware do when VBUS has disappeared? I'm not familiar with the STM32 USB library, and have only dealt with th...
I am looking at this RF connector. I see that insulation resistance and breakdown voltage are specified, but no voltage rating: I have two questions, one functional and one safety. Functionally...
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...
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...
First, note this only applies when the line to the input power source is long enough to have significant inductance. If the power source is on the same circuit board, then this isn't an issue. Th...
The main problem with a question along the lines of "how do you design a product for medical applications" is that it's way too broad. You cannot reasonably write a somewhat complete answer because...
Using voltage as a way of saying "I'm dealing with voltage here" is pointless - most electronics questions do. I think the voltage vs current tags are however relevant in the case when you need to...
I agree with everything said. I didn't really consider until now that Codidact (unlike Someplace Else) supports case-sensitive tagging. So in addition, perhaps add a note regarding the following: ...
how much higher can i go in current ripple RMS None, of course, at least if you want to rely on anything else the datasheet says. The heating is a function of the RMS current. No, you don't get ...
This graph - MLCC temperature rise vs ripple current RMS & frequency If I had a 10 us current spike every 100 000 us (akin to a half-sine wave and then the rest of 9999 sine waves missing), ...
First question I have is why conductor/earth voltage rating for DC is specified lower at 0.9kV? Imagine two cables running side to side. To get from one cable to the other, an electron would h...
Do you supply the PSON# signal before or after the main power comes on, or before connecting the load? Looking at the datasheets, the correct sequence is VAC power on, then PSON# signal to ground,...
Does C have a mechanism which lets me mark a section of code such that breakpoints are somehow ignored or not allowed just in that section? Generally compilers are completely unaware of debugg...
When measuring signals at different points on the skin of the body, you don't usually want to connect the victim patient to ground. Usually you use an extra electrode connected some distance away ...
I agree with this approach. Categories should only be created when they are expected to have reasonable traffic. A category with only chirping crickets is an anti-advertisement. Take a look at t...
CMRR design is key to rejecting grid e-fields that impose noise onto EMG, EKG,EEG amplifiers. This includes all series Zs of cable balance and Amp CMRR. For this reason >100 dB CMRR are requ...
