Hi,
I have a pretty simple circuit, but I need to send an output PWM signal through the same place I'm getting my voltage. The voltage is DC, so I figure since my PWM is an AC current, I can use a low pass filter to send the signal through, while getting DC current from the supply. I'd prefer to use a capacitor/resistor filter rather than an inductor, but I'm unsure how I would go about creating one for this particular circuit.
For an inductor, I'm guessing I'd put it on the path to VCC of my microcontroller? Where would I do it with a capacitor?
Thanks!!
