Hi,

my understand is that electronics equipment encloser is usually connected to earth. i saw in some circuit design the board ground (digital/analog) is connected to screw mounting holes with 1M ohm and some small capacitors. can i ask what's the purpose of the resistor and capacitor? why not use smaller value for the resistor? thanks.

Hi,
I think to collect the better links in a bookmark folder is a must for an "interest", but it can be a probleme too_ i.e. if you need a reinstallation and it will forgeted too copy/rescue in case of virus attacke and reformatting...
I think, its better to storage some edited materials as doc-file or even make regulate a saving/backup copy.

Oh, so it is to isolate the noise picked up the the chassis ground and the circuit ground?
So why use a small cap?
Isnt it better to use a large cap?
