Hello Everyone!!
I am getting confused with LC-filters (also with emi-filters). Capacitors eliminate noise from signals. It bypass it to ground or noise source.
The inductor does not allow high frequency to pass and also reduce current noise and I think it is correct but not sure??
Inductor reactance are linearly promotional to frequency and it is opposite for capacitive reactance. I am also familiar with frequency resonance ...
I studied first order RC-filters one time. I know how they work.
When I think of LC filters first it comes to my mind is that capacitor limit frequency but not sure what the inductor does?? Signals are DC square wives!!
Could you please tell me which one limit frequency and which one eliminate noises ??
