Connecting passive low pass filters in series, reduces the dc voltage.
Maybe it is very simple but would you explain a little bit to me about the low pass filters effects on dc.
Filters don't reduce dc without a load by the way.
Source 12VDC(with little ripple)
Load 20 Ohm.
Filter section(RC lowpass passive)
If i take the output of the first filter,
500 Ohm 1mF (cutoff around 0.3Hz)---Out ~7VDC---
If i take the output of the second filter also current draw reduces a lot.
500 Ohm 1mF ---Out ~0.20VDC--- etc.
Thank you.
