Abstract

PROCEDIMIENTO PARA LA DEMODULACION DE SEÑALES MODULADAS EN FRECUENCIA DONDE SON FILTRADAS POR MEDIO DE FILTRO PASO BAJO Y DONDE A CONTINUACION SON OBTENIDAS MEDIANTE MULTIPLICACION COMPLEJA (MODULACION DE RETARDO) DEL INCREMENTO DE FASE DESEADO Y CON ELLO SE OBTIENE LA SEÑAL TRANSMITIDA, CARACTERIZADO PORQUE, LA SEÑAL DE RECEPCION EXPLORADA SE SOMETE A UN FILTRADO CON UN FILTRO DE BANDA Y DISPONIENDO ESTE FILTRO DE COEFICIENTES DE VALOR COMPLEJO. PROCEDIMIENTO PARA SU UTILIZACION DE FORMA MUY ADECUADA DE COSTE, EN PARTICULAR EN LA DEMODULACION DE SEÑALES UKW-FM.
