OK, after doing some reading and learning up the basic calculation on RC filters (thx to Nigel's recommendation), i finally used the RC filter to filter PWM pulses.
However, i have several problems
Firstly, the ripples are too large or if i increase my capacitor or resistor value, my PWM pulses voltage seem to have dropped from 5V to 1V after being filtered.
If there anyway i can maintain my voltage level with slight ripples?
Thx.
