Hi all,
I'm trying to build a low-pass RC filter, but I'm not sure if I've picked out the right values for the resistor and capacitor. I'm trying to extract the sine wave from a sine wave modulated PWM. The PWM switches at 20kHz and the sine wave is anywhere between 1 to 100 Hz. I want to use a 10k ohm resistor and a 20nF capacitor. Do these values sound ok?
Thanks!
