Hi folks!
I have a PIC microcontroller which is generating a PWM signal of 5 kHz. It has a varying dutycycle so I can draw an analog signal, which has to be smoothened. For that I need a low-pass filter, but I dont know which values to pick for R and C. Can you guys help?
If you need more info, feel free to ask!
