Radio Receiver for receiving a Signal of Television without prejudice to Quadrature Amplitude Modulation (QAM) or vestigial sideband (VSB).

摘要

A Radio Receiver includes a First and a Second Chain of intermediate Frequency amplifiers that respectively provide an intermediate Frequency and a Second Order responseThe Signal to a digital television (DTV) selected for Reception; First and segundoconversores Analog to digital to digitize the first and second Intermediate Frequency responsesEnd of qampara; sincrodinadores Circuits generate flows of data realese Imaginary Code of QAM symbols interspersed sincrodinizando First frequency response intermediafinalDigital baseband,If the signal is selected a DTV QAM Signal; and sincrodinadores devsb Circuits to generate a Flow of real samples of Code symbols interspersed sincrodinizand VSBThe second response or final Digitized Intermediate Frequency to baseband, provided that the signal is a Signal of DTV VSB.The First s egunda Chains of intermediate Frequency Amplifiers share at least one osciladorlocal.
