Abstract
An SDARS receiver includes an analog front end configured to receive a composite signal. An A/D converter is coupled to the analog front end and converts the signal to a digitized signal. A digital down converter (DDC) is coupled to the A/D converter and down converts the digitized signal to a down converted signal. A demodulator demodulates the down converted signal. The receiver includes a digital automatic gain control (DAGC) coupled to an output of the A/D converter and before the demodulator. An automatic gain controller is coupled to the DAGC for providing an automatic gain control signal.
