Abstract
Disclosed is a device for filtering electrical noise in a vehicle. The device includes a housing connectable to the vehicle, a variable capacitor, an input signal line coupled to the variable capacitor and couplable to a first conductor that carries electrical signals along with electrical noise of a given amplitude, and an output signal line coupled to the variable capacitor and couplable to a second conductor. When the input signal line is coupled to the first conductor and the output signal line is coupled to the second conductor, the second conductor carries the electrical signals along with electrical noise of reduced amplitude within a range of frequencies. The device also includes a tuner coupled to the housing and configured to adjust a capacitance of the variable capacitor, wherein adjusting the capacitance of the variable capacitor adjusts the range of frequencies.
