Abstract: In one aspect, the present invention includes an automatic volume control (AVC) circuit to receive a demodulated signal and provide an output signal at a substantially constant volume. The circuit may be implemented in hardware, software, and/or firmware to perform digital demodulation, programmable amplification, and high pass filtering to provide a substantially constant volume output.

Abstract: In one aspect, the present invention includes a method for receiving an amplitude modulation (AM) signal in a receiver and performing a coordinate rotation digital computer (CORDIC) operation in obtaining a demodulated AM signal. The demodulated AM signal may be obtained from a magnitude output of the CORDIC operation or as a real output of a multiplication between a complex baseband signal and a demodulating carrier signal generated in a feedback loop.

Abstract: A frequency modulation (FM) radio receiver includes a processing unit that may generate a magnitude value corresponding to a signal strength of each of a plurality of digital samples of a received FM signal. The receiver also includes a noise estimation unit that may filter the magnitude values using a high pass filter and may generate a noise value representative of a noise portion of the received FM signal based upon the filtered magnitude values.
