A receiver system and method for detecting and attenuating noise in a predetermined frequency range. The system includes at least one antenna, at least one filter, at least one automatic gain control device, and at least one processor. The at least one antenna receives at least one signal that includes at least one AM signal. The signal passes through the at least one filter. The at least one automatic gain control device adjusts the gain of the at least one signal to attenuate noise in the at least one signal. The at least one processor performs the steps including detecting when said noise is within a predetermined frequency range, and commanding the at least one automatic gain control device when the detected noise is within the predetermined frequency range, such that the automatic gain control device attenuates the noise that is within the predetermined frequency range. |
