how to reduce the ac voltage? from a mix signal?
suppose that there is a mix signal (with 60vdc+110vrms). now i want to completely block the dc component (OBVIOUSLY I NEED A CAPACITOR BUT)what should be the specifications* of the capacitor. and if i want to reduce the the dc component to 15v then what should be the specification of the capacitor.
i need the complete calculation/procedure required to find each of the value of the capacitor.
*by specification i mean
2- voltage rating
3- type (ceramic/electrolytic etc)
