Abstract

UN METODO Y UN SISTEMA DE MODULACION CONTINUA POR DESPLAZAMIENTO DE FASE CON CONTROL PERFECCIONADO DEL ESPECTRO, EN QUE, PARA CADA UNA DE LAS COMPONENTES EN FASE Y EN CUADRATURA, IMPULSOS SEMI-CONSENOIDALES ADYACENTES DE LA MISMA POLARIDAD ESTAN UNIDOS POR UNA SEÑAL DE MODULACION DE TRANSICION CONTINUA QUE MANTIENE LA CONTINUIDAD DE LA FORMA DE ONDA Y DE SU PRIMERA DERIVADA POR LO MENOS. CUANDO ESTO SUCEDE, LA OTRA SEÑAL COMPONENTE ES AJUSTADA PARA MANTENER CONSTANTE LA SUMA VECTORIAL DE LAS SEÑALES COMPONENTES.
