摘要： The disclosed embodiments relate to a system that processes a received signal. An exemplary embodiment of the system comprises a receiver circuit that is adapted to receive the received signal and separate an out-of-band data signal corresponding to an out-of-band frequency spectrum from the received signal, an analog-to-digital (A/D) converter that converts the out-of-band data signal to a digitized out-of-band frequency spectrum signal, and a circuit that is adapted to identify data corresponding to an out-of-band data channel within the digitized out-of-band frequency spectrum signal.

摘要： A method and apparatus for isolating a noise intolerant device, e.g., a phase-lock loop of a tuner within a television receiver, from source of noise. In one embodiment, the apparatus isolates a phase-lock loop integrated circuit (IC) from the bus, by providing an isolation buffer that allows the receiver to only pass data to the tuner's phase-lock loop IC when a tune command is issued by a processor. When not being tuned, the IIC lines to the tuner are held HIGH by a buffer until needed again to perform the tuning function. This allows the demodulation circuitry to use a setting for a carrier tracking-loop that optimizes bit error rate performance.

摘要： The method and apparatus according to the present invention teaches a way to employ a pair of inexpensive switch IC's by improving isolation using a tuned diode shunt on the potential leakage path that exists between the two inputs when the IRD is in the legacy LNB Mode. In particular, the present invention teaches a method and apparatus of providing a signal path between a first input and a second signal processor. The second signal processor can further be coupled to a second input. When the second processor is coupled to the second input, the signal path is decoupled from the second processor and coupled to ground using a pin diode.

摘要： A receiver for processing a VSB modulated signal containing terrestrial broadcast high definition television information includes an input analog-to-digital converter (19) for producing a digital datastream. A symbol timing recovery and segment sync recovery network (24; FIG. 3, 4) develops a properly timed sampling clock for the digital converter (19). The symbol timing recovery network (310) responds to an output from the segment sync recovery network (328), which in turn responds to an equalized signal from an adaptive channel equalizer (34). A controlled oscillator (336) generates the sampling clock for the digital converter. A control network (340, 344, 348; FIG. 3) shifts the frequency range of the oscillator to maintain desired linear operation to enhance symbol timing acquisition.
