Statement:
Capacitors can be used to store energy or to filter signals. Some examples include filtering out AC [used to reduce the "ripple" of a DC power supply] or filtering out a DC. In filtering out a DC, only time-varying signal will pass through a capacitor. The circuit on either side of the capacitor can be at different DC voltages.
Questions
Can someone explain to me the background on Filtering out AC, and how it is
Thanks so much,
JL

And similarly the concept of filtering out DC whereused to reduce the "ripple" of a DC power supply?
only time-varying signal will pass through a capacitor?
