Please a circiut or IC for cutting current's noise

[Overkillica]

Well, I hope you've understood my problem. Let's put it this way, I connect
an adaptor that converts the 120 ACV to 12 DCV, but in this adaptor, there's
only the usual thing, resistors, Diodes, Capacitors, a Transformer, but my
questions is: Is there any circuit, IC (CHIP), that cuts all or at least
part of the noise that's in the current.
I hope someone can help me. Thanks.
Bye.

What you realy need is a well designed powersupply. I don't think a
simple easy IC will do the job to any type of very good perfection.

The easiest solution is a good battery. There are some lab supplies
around made by Hammond and Lamda that are extreemly clean, and will do
an excellent job.

Noise or hum? There are schematics for simple regulated power supplies using
wall adapters in the "Various Schematics..." FAQ at the site below.

You can also purchase a device called a line conditioner with broadband noise
filter.The noise may be actually coming from any noise from the outlet, going
into the circuit. The line copnditioner plugs into the wall, the transformer
plugs into the line conditioner.

Try a ferrite bead,wrapping the wire around the bead will increase its
effect.
Remember the wire must be as tight as possible inside the bead tho.
