摘要： According to one aspect, a mixed-signal tuner for analog and digital TV reception incorporates a demodulator for analog TV, employing various features for resolving limitations of the analog circuitry and for achieving compatibility with various global TV standards. Such features, which may be present in one or more embodiments, include the use of a variable sample rate in all digital clocks for frequency planning, and use of a microcontroller (MCU) to control various circuitry of the tuner.

摘要： According to one embodiment, a method for updating filter values of an image canceller is provided. The method may include determining a channel-to-image (C/I) ratio between a channel signal and an image signal at the canceller input and generating a gain control value based at least in part on the C/I ratio. Then correlations between the channel signal and the image signal at the canceller's input and output can be generated, along with a gear control value based at least in part on a ratio between the correlations. In turn, one or more filters of the canceller can be updated using the control values.
