Abstract:
A noise attenuating system for suppressing noise on circuit board transmission lines, said noise attenuating system comprising:a circuit board having a first side and a second side and at least one conductive transmission line;a first ferrous member attached to said first side of said circuit board, wherein the ends of said first ferrous member protrude through a first and second aperture of said circuit board; anda second ferrous member attached to said second side of said circuit board and contacting said first ferrous member outside of said first and second apertures said second ferrous member substantially opposed from said first ferrous member, such that at least one conductive transmission line is at least partially disposed between said first ferrous member and said second ferrous member, wherein noise on said at least one conductive transmission line is absorbed and suppressed by said first ferrous member and said second ferrous member, said first ferrous member and said second ferrous member being fastened to said circuit board utilizing polymer retainers.
