ABSTRACT:
Systems and methods are provided for suppressing radio interference from a noise source having an operating frequency. One system includes memory for storing a threshold signal strength, a re-configurable filter for selectively filtering signals of a harmonic of the operating frequency, and a controller. The controller is configured to compare a signal strength of a received signal to the threshold signal strength and turn ON the re-configurable filter if the signal strength of the received signal is less than or equal to the threshold signal strength. A method includes determining a noise signature for the motor vehicle and associating a signal strength threshold with the noise signature. The method further includes comparing a signal strength of a tuned radio station to the signal strength threshold and turning ON the filter if the signal strength is less than or equal to the signal strength threshold.
