Statement
Capacitors can be used to store energy or to filter signals. Example, filtering out AC is used to reduce the "ripple" of a DC power supply. Also Filtering out DC: Only time-varying signal will pass through a capacitor. The circuit on either side of the capacitor can be at different DC voltages.
Question
Can someone explain to me in general term [or in detailed], what filtering out AC or DC means?
Thanks,
Jeff
