Hello. First time poster. I didn't know where exactly I should post this so if I'm in the wrong area I'd appreciate a nudge in the right direction. Otherwise I'm having a little trouble coming up with an answer to a question about speakers. I currently have a PA system in my vehicle to do...

In my circuit (not relevant to the purpose of the question, but if you want I can post it) I have a PWM signal input to a gate driver, two external mosfets (HS and LS) and a load resistor (it's a classic half bridge configuration). I need to measure the efficiency of the system by doing...

Hi Everyone, I am trying to define the most suitable current source for my application. Essentially, I need a high stability current source to feed Hall probes sensors. The probes' nominal current is 10 mA. A stability of 100 ppm (i.e., 1 uA) for short term (a few hours) is desired. Usually, I...

I found this paper to be useful. It says: So in my case for one cycle, I can't have an integer N that matches both 50 and 60 Hz and possible fluctuations. In the microcontroller, the plan I have is to set an ADC triggered by a timer for a fixed sampling frequency. I can also use DMA or double...
