Abstract:
A tuner includes, in part, one or mixers, one or more filters, one or more variable gain stages, one or more analog to digital converters, and a baseband processor. Each filter is responsive to an associated mixer's output signal. Each variable gain stage is responsive to an associated filter's output. Each analog-to-digital converter is adapted to convert the output signal of an associated variable gain stage to a digital signal. The baseband processor is responsive to the digital signal supplied by the analog-to-digital converter(s). The baseband processor is further configured to supply a signal to be demodulated by a processing unit external to the integrated circuit. The baseband processor performs no or a fraction of the required demodulation functions. The processing unit may be a central processing unit or a graphical processing unit.
