Hello,
I am having a hard time in understanding the use of Op AMps in filtering circuits, I read that it is useful because it can provide filtering of very low frequencies but i cant understanding how is it done, and we are using the same capacitor in Op Amp filter (Active filter) as well as in passive filters so how is Op Amp making it special?
