Abstract:
A radio receiver comprising:an input portion having a tuner for selectively receiving an input modulated signal and mixing the input modulated signal with a local signal to generate an intermediate frequency signal; a filter bank for receiving the intermediate frequency signal and generating a plurality of sub-band signals, each of the plurality of sub-band signals having a predetermined frequency range; a monitoring circuit coupled to the filter bank, the monitoring circuit measuring a predetermined parameter of each of the sub-band signals and providing a plurality of parameter signals in response thereto; a control circuit coupled to the monitoring circuit for receiving the plurality of parameter signals, the control circuit provides one or more control signals which determine a percentage of each of the sub-band signals which is permitted to be coupled to an output terminal; a summing circuit coupled to the output terminal for receiving the percentage of each of the sub-band signals from the monitoring circuit and adding the percentage of each of the sub-band signals to provide a filtered output signal; and a demodulator coupled to the summing circuit for demodulating the filtered output signal to provide an audio output signal with optional data.
