Abstract

UN CIRCUITO DE MODULACION DE TECLADO DE INVERSION DE BIFASE (BPSK) PARA UN SISTEMA DIGITAL DE TRANSMISION DE DATOS ES CAPAZ DE IMPEDIR LA DISTORSION DE LA SEÑAL AUN EN POSICIONES DE INVERSION DE FASE EN UNA AMPLIFICACION DE ENERGIA DE UNA SEÑAL DE MODULACION AL PROPORCIONAR UNA CARACTERISTICA DE ENVOLTURA CONSTANTE A LA SEÑAL DE MODULACION DURANTE LA MODULACION. EL CIRCUITO DE MODULACION BPSK TIENE UNA ENTRADA HORARIA (100) QUE RECIBE UN RELOJ DE SISTEMA, MEDIOS DE GENERACION DE DATOS (10) CONECTADOS PARA RECIBIR AL RELOJ DEL SISTEMA PARA PROPORCIONAR DATOS DIGITALES ALEATORIOS EN SINCRONIZACION CON EL RELOJ DEL SISTEMA, MEDIOS DE CONVERSION DE DATOS (20) CONECTADOS PARA RECIBIR AL RELOJ DEL SISTEMA Y UNA SALIDA DE LOS MEDIOS DE GENERACION DE DATOS (10), PARA PROPORCIONAR UN COMPONENTE DE SEÑAL EN FASE Y UN COMPONENTE DE SEÑAL EN FASE CUADRUPLE EN SINCRONIZACION CON EL RELOJ DEL SISTEMA Y MEDIOS DE MODULACION (30) CONECTADOS PARA RECIBIR LOS COMPONENTES EN FASE Y EN FASE CUADRUPLE DESDE LOSMEDIOS DE CONVERSION DE DATOS (20), PARA PROPORCIONAR UNA SEÑAL DE MODULACION DE FASE DE ENVOLTURA COSNTANTE EN UNA SEÑAL DADA DE ONDA PORTADORA PARA LA TRANSMISION DE DATOS DIGITALES. EL COMPONENTE DE SEÑAL EN FASE ES PROCESADO EN UNA MODULACION DE EQUILIBRIO DOBLE CON LA ONDA PORTADORA Y EL COMPONENTE DE SEÑAL EN FASE CUADRUPLE ES PROCESADO EN UNA MODULACION DE UN SOLO BALANCE CON UNA SEÑAL DE CAMBIO DE FASE DE LA ONDA PORTADORA.
