Abstract
UNA INSTALACION DE TRANSMISION DE TELEVISION Y RECEPTOR DE TELEVISION CORRESPONDIENTE.UNA SEN/AL DE DBS MODULADA EN FRECUENCIA, DE BANDA ANCHA, ES RECIBIDA POR UNA ATENA, CONVERTIDA EN FRECUENCIA DE UN CONVERTIDOR REDUCTOR Y APLICADA A LA ENTRADA DE UNA UNIDAD DE CONVERSION. LA UNIDAD DE CONVERSION TIENE UN SINTONIZADOR, UN PASO DE FI Y UN DESMODULADOR DE FRECUENCIA PARA PRODUCIR SEN/ALES DE VIDEO DE BANDA DE BASE QUE, DESPUES DE ATENUACION, SON APLICADAS A UN MODULADOR DONDE LAS SEN/ALES DE VIDEO SON MODULADAS EN AMPLITUD SOBRE UNA PORTADORA DE IMAGEN PROCEDENTE DE UN OSCILADOR. LA PORTADORA MODULADA ES APLICADA A TRAVES DE UN FILTRO DE BANDA LATERAL RESIDUAL Y UN SUMADOR A UNA SALIDA. LOS TRENES DE IMPULSOS DE SONIDO/DATOS PRESENTES EN LA SEN/AL DBS SON SEPARADOS EN UN PASO Y TRATADOS EN UN APARATO DONDE LOS TRENES DE IMPULSOS DE SONIDO/DATOS SON EXTENDIDOS.
