Topic: RC Filter turns PWM to pure variable wave (Read 4345 times) previous topic - next topic


I didn't know where to put this so I put it here  :D
A simple 1K resistor in series with a 33uf capacitor turns PWM into a pure wave!
Just wanted to tell everyone how easy it is.
Avoid throwing electronics out as you or someone else might need them for parts or use.
Solid state rectifiers are the only REAL rectifiers.
Resistors for LEDS!


Sorry but it is a bit more complicated than this. Using a simple RC filter is only a simple roll off filter and doesn't result in a "pure" wave.
