Abstract

EN UN DEMODULADOR PARA SEÑALES DE DATOS DE RADIO QUE SON TRANSMITIDOS EN FASE DE CLAVE DE UN PORTADOR AUXILIAR BAJO PRESION, SE PREVIENE LA APARICION DE TIEMPO DE TRANSICION MEDIANTE LA CONVERSION DE LA SEÑAL DE FRECUENCIA PORTADORA AUXILIAR RECIBIDA EN UNA PRIMERA SEÑAL (A) DE ONDA CUADRADA Y MEDIANTE LA FORMACION DE UNA SEGUNDA SEÑAL DE FRECUENCIA PORTADORA AUXILIAR QUE SE TOMA DENTRO DE UN TIEMPO TAL, QUE LA RELACION A LA PRIMERA SEÑAL DE ONDA CUADRADA SUPONE UNA COMPARACION ENTRE LAS DOS SEÑALES DE ONDA CUADRADA QUE SUMINISTRAN INFORMACION DE FASE EN LA PRIMERA SEÑAL (A). LA DEMODULACION PUEDE SER REALIZADA SOLAMENTE A PARTIR DE COMPONENTES DIGITALES.
