Abstract

A DIGITAL RADIO RECEIVER IS DESCRIBED. THE DIGITAL RECEIVER (100) OF THE PRESENT INVENTION CONTEMPLATES A DIGITAL RADIO RECEIVER WHICH OPERATES ON A RECEIVED ANALOG SIGNAL WHICH HAS BEEN CONVERTED TO A DIGITAL FORM AFTER PRESELECTION AT THE OUTPUT OF THE ANTENNA. THE DIGITAL RECEIVER (100) OF THE PRESENT INVENTION COMPRISES A PRESELECTOR (106), A HIGH-SPEED ANALOG-TO-DIGITAL (A/D) CONVERTER (108), A DIGITALLY IMPLEMENTED INTERMEDIATE-FREQUENCY (IF) SELECTIVITY SECTION (110) HAVING AN OUTPUT SIGNAL AT SUBSTANTIALLY BASEBAND FREQUENCIES, AND DIGITAL SIGNAL PROCESSOR (DSP) CIRCUIT (120) PERFORMONG DEMODULATION AND AUDIO FILTERING. THE RADIO ARCHITECTURE OF THE PRESENT INVENTION IS PROGRAMMABLY ADAPTABLE TO VIRTUALLY EVERY KNOWN MODULATION SCHEME AND IS PARTICULARLY SUITABLE FOR IMPLEMENTATION ON INTEGRATED CIRCUITS. (FIG. 1)
