摘要

Systems and methods for selecting digital content channels using low noise block converters including digital channelizer switches systems and methods in accordance with embodiments of the invention include converting satellite signals to an intermediate frequency signal for content decoding,And selecting modulated digital date within the satellite signals for content decoding using digital signal processing.One embodiment includes the system configured to select at least one content channel from an input signal including a plurality of content channels modulated onto the carrier.The system including: an input configured to receive an input signal comprising the plurality of content channels modulated on the carrier; a mixer configured to down convert the plurality of content channels to an intermediate frequency signal; digital channelizer switch including: high speed. Og to digital convert configured to digitize the intermediate frequency signal; digital channeliZer configured to digitally tune the content channel from the digitized intermediate frequency signal; and a high speed digital to analog converter configured to generate an analog output signal using the content channel digitally tuned from the digitized intermediate frequency signal by the digital Channelizer._ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ translation of the summary summary invention patent: "systems. Methods to select channels of digital content using blockers of low noise converters including digital switches plumbers".Systems and methods of the invention include conversion of the agreement details of satellite signals to an intermediate frequency signal for the content of decoding and selection of digital data modulated among the satellite signals to the contents decoding using the p Rocessamento digital signal.A method includes a system configured to select at least one channel of the content of an input signal that includes a plurality of channels of content modulated on a carrier.The system includes: an input configured to receive an input signal comprises a plurality of channels of content modulated on a carrier; a mixer configured to convert down the plurality of content channels to an intermediate frequency signal; a Fula Tator plumber digital.Analog to digital converter including: a high speed configured to scan the signal of intermediate frequency, a digital channel configured to tune a channel content of the intermediate frequency signal digitalized, and an analog to digital converter of al. TA speed configured to generate an analog output signal.Using the channel content digitally tuned from the intermediate frequency signal digitized by a digital.
