Abstract

DURANTE LA RECEPCION DE TELEVISION VIA TERRESTRE, EN GENERAL UNA PRIMERA CONVERSION EN UNA PRIMERA FRECUENCIA INTERMEDIA ES SEGUIDA POR OTRAS CONVERSIONES A UNA SEGUNDA FRECUENCIA INTERMEDIA. DURANTE LA RECEPCION DE TELEVISION POR SATELITE, UN DEMODULADOR FM-PLL EXTRACTA LA SEÑAL DE BANDA BASE A PARTIR DE LA SEÑAL DE SATELITE CONVERTIDA EN UNA PRIMERA FRECUENCIA INTERMEDIA. PARA ESTE OBJETIVO, SE UTILIZAN GENERALMENTE DOS SINTONIZADORES SEPARADOS. EL OBJETIVO DE LA INVENCION ES SUMINISTRAR UN SINTONIZADOR COMUN TANTO PARA LA RECEPCION DE TELEVISION TERRESTRE COMO VIA SATELITE CON UN CIRCUITADO TAN PEQUEÑO CON SEA POSIBLE. LA SEGUNDA ETAPA (M2) DE MEZCLADO SE CONECTA COMO UN MEZCLADOR PARA LA CONVERSION A LA SEGUNDA FRECUENCIA INTERMEDIA DURANTE LA RECEPCION DE TELEVISION TERRESTRE Y SE CONECTA COMO UN COMPONENTE DE UN DEMODULADOR FMPLL (30) DURANTE LA RECEPCION DE TELEVISION VIA SATELITE. LA INVENCION ES PARTICULARMENTE ADECUADA PARA RECEPTORES DE TELEVISION Y GRABADORES DE VIDEO QUE RECIBEN DE FORMA SELECTIVA LA SEÑAL DE UNA ANTENA TERRESTRE O DE UNA ANTENA DE SATELITE.
