Does anyone know any circuits for filtering out noise from your power supply lines? I'm trying to clean up the 12vdc in my robot. It is powering a PC which introduces noise on the power lines. I hooked up an Oscope and there is a specifc frequency and ripple it introduces. Knowing this, is their a circuit I can use to filter this along with some formulas for figuring out the values of the components?
Thanks!!
