Patent ID: 8116711

Claim:
A receiver system comprising: at least one antenna that receives at least one signal; at least one filter in communication with said at least on antenna, wherein said at least one signal passes through said at least one filter; at least one automatic gain control device in communication with said at least one filter, wherein said automatic gain control device adjusts the gain of said at least one signal to attenuate noise in said at least one signal; and at least one processor in communication with said at least one automatic gain control device, wherein said at least one processor performs the steps comprising: detecting when said noise is within a predetermined frequency range, said predetermined frequency range being determined by at least one processor filter; and commanding said at least one automatic gain control device to attenuate said noise within said predetermined frequency range when said detected noise is within said predetermined frequency range, such that said automatic gain control device attenuates said noise that is within said predetermined frequency range, wherein said predetermined frequency range is one of approximately sixty hertz (60 Hz) and multiples thereof and approximately fifty hertz (50 Hz) and multiples thereof.
