I mean depends on the context, in the specific case which i was thinking of it is signal but usually its noise. I have mainly worked with ac and dc signal coupling so thats why both sre signals for me when i think if it.

Well youre not far off. They are used to filter ac, not convert it. They act as low-pass filters which means if you have a setup which is a 100khz low-pass filter it means it only lets through frequencies that are under 100khz. There are of course more accurate but complicated ways of explaining this but that is out of scope for this comment. Also nothing is perfect in the real world but you can calculate how much of the signal it lets through.

Well by attenuate it a bit you mean they pretty much filter ac out if you have the right capacitance and resistance values as capacitors act like low pass filters.

Ide(get it) say that vim is an ide. Now kill me swarms of people who disagree, i have nothing to lose and want to die on this hill.

History is a really important subject. I think a lot of people just dont undrstand this conflict. And a lot of people who do understand it are evil. Basically nobody is in the right. Where do you put the israelis who lived there for generations? Where do you put the palestanians who lived there for several generations? How do you solve the religious and cultural conflicts. Its an extremely complicated war. Not to mention that its not the civilians who start a war its the stupid leaders and terrorists aka hamas, us, israeli government. Well this is my view i may have got things wrong but i dont know the exact details of it.
