ABSTRACT:
A noise attenuating system for suppressing noise on circuit board transmission lines is provided. A first ferrous member is attached to a first side of the circuit board and a second ferrous member attached to a second side of the circuit board. The second ferrous member is substantially opposed from the first ferrous member, such that conductive transmission lines are contained between the first ferrous member and the second ferrous member. Transmission line interference is absorbed and suppressed by the first ferrous member and the second ferrous member. In a preferred embodiment, substantially all traces which enter and exit the circuit board on a connector pass between the first ferrous member and the second ferrous member. Apertures in the circuit board allow the ferrous members to adjoin forming a ferrous core.
