Patent ID: 7515078

Claim:
A radio receiver front end for receiving a received radio signal having a plurality of channel signals, each of the plurality of channel signals being modulated at one of a corresponding plurality of carrier frequencies, and for converting a selected one of the plurality of channel signals into a digital baseband signal, the radio receiver front end comprising: a channel selector, for producing a control signal that corresponds to a selected one of the plurality of channels; a local oscillator, operatively coupled to a reference oscillation, for producing a local oscillation signal at a local oscillation frequency, the local oscillation frequency based on the control signal; an analog to digital converter module, operatively coupled to a modulated signal, the modulated signal operably coupled to the received radio signal, and a variable frequency clock signal that varies as a function of the local oscillation frequency, the analog to digital converter module for producing a digital signal; and a programmable decimation filter, operatively coupled to the digital signal and the control signal for producing the digital baseband signal at a substantially constant frequency.
