Abstract
A system for detecting interference includes an automatic gain control (AGC) module, a digital signal processing (DSP) module, and a control module. The AGC module selectively generates a gain-locked signal when an input signal is received. The DSP module communicates with the AGC module and selectively generates a sync-detect signal when the input signal is received. The control module communicates with the AGC module and the DSP module, and generates a control signal when the DSP module does not generate the sync-detect signal within a predetermined time after the AGC module generates the gain-locked signal.
