Abstract
RECEPTOR PARA SEÑALES DE BANDA EXTENDIDA. EL CODIGO ES ALMACENADO EN EL RECEPTOR, EL CUAL ES EMPLEADO POR MEDIO DEL TRANSMISOR PARA FINES DE EXTENSION DE LA BANDA. SE RECUPERA LA MODULACION DE LA SEÑAL RECIBIDA. LOS COMPONENTES I Y Q DE LA SEÑAL PORTADORA MODULADA SON GENERADAS PARA FINES DE CONTROL. LAS SEÑALES RECIBIDAS SON DIGITALIZADAS (4). ESTAS SEÑALES TIENEN UN VALOR U OTRO SEGUN QUE LA SEÑAL QUE SE DIGITALIZA SUPERE O NO UN UMBRAL. LA SEÑAL RESULTANTE SE MUESTRA, Y LA SEÑAL OBTENIDA SE APLICA A UN CONTADOR, PROCESANDOSE POSTERIORMENTE. LA SEÑAL PORTADORA RECIBIDA EN PRINCIPIO ES CONVERTIDA AL VALOR IF FUNDAMENTAL PARA SER DIGITALIZADA; Y EL CONTADOR, ES PERIODICAMENTE REAJUSTADO.
