Abstract: A method and apparatus for demodulating different type of signals having at least a portion of overlapping frequency ranges is provided. The method and apparatus receives at least one a broadcast signal and a home networking signal, wherein the frequency range of the broadcast signal overlaps the frequency range of the home networking signal. The system further determines if the received signal is a broadcast signal or a home networking signal and provides the respective signal to a demodulator for demodulation.

Abstract: The present invention concerns a system and associated method for providing attenuation of a received signal in a two-way communication circuit without the use of a separate switchable attenuator. Specifically, the attenuation provided by a transmit/receive switch set to the transmit position during reception is used to provide attenuation to a signal reception path.

Abstract: An apparatus such as a television signal receiver provides an AGC function which reduces cross-modulation distortion. According to an exemplary embodiment, the apparatus includes first and second amplifiers coupled in series and a gain control circuit. The gain control circuit controls the gains of the first and second amplifiers in response to the magnitude of the input signal. The gain of the first amplifier remains substantially unchaged at a first level while the magnitude of the input signal is within a first range. The gain of the second amplifier is gradually reduced in the first range. The gain of the first amplifier remains substantially unchaged at a second level, which is lower than the first level, while the magnitude of the input signal is within a second range. The gain of the second amplifier gradually reduced in the second range. The gain of first amplifier is gradually reduced at least in part of a third range while the magnitude of the input signal is within the third range.
