20110133840 | PRE AND POST FILTER AUTOMATIC GAIN CONTROL WITH BOUNDED PRE-FILTER GAIN CONTROL - An electronic circuit includes a first variable gain amplifier for amplifying a signal at an input to provide a first amplified signal; a filter receiving the first amplified signal to provide a filtered signal; a second variable gain amplifier for receiving and amplifying the filtered signal; a second gain control bock, to provide at least one gain control signal derived from the filtered signal, one of the at least one gain control signal to control the gain of the second variable gain amplifier; and a bounding block for receiving one of the at least one gain control signal from the second gain control block, and for generating therefrom a bounded gain control signal to control gain of the first variable gain amplifier. | 06-09-2011 |
20130223572 | DIGITAL SIGNAL PROCESSOR WITH ADJUSTABLE DATA RATE AND METHODS THEREOF - As a digitized representation of an intermediate frequency television signal moves through a demodulator it undergoes a number of processes, including conversion from an analog signal to a digitized data, digital signal processing of the digitized data, and the like. The rate at which the digitized data moves through the digital signal processor of the demodulator for processing is referred to as the data rate of the DSP. The demodulator can vary the data rate based on a selected television channel, thereby reducing the level of interference at the demodulator resulting from noise. | 08-29-2013 |
20130293781 | METHOD AND APPARATUS FOR EXTRACTING A DESIRED TELEVISION SIGNAL FROM A WIDEBAND IF INPUT USING RE-SAMPLING - Various embodiments are described herein for a universal television receiver that is capable of processing television channel signals, that are transmitted according to a variety of broadcast standards, to provide video and audio information for a desired television channel signal. The processing includes producing a coarse channel signal that includes a desired television channel signal and then applying resampling techniques to adjust a normalized bandwidth of the desired television channel signal to generally correspond to the normalized passband of a main filter that is used for each of the broadcast standards. | 11-07-2013 |
