Abstract

EN UN CIRCUITO DEMULADOR DIFERENCIAL/DETENCION, UNA SEÑAL MODULADA PSK SE COMPARA CON UNA SEÑAL LOCALMENTE OSCILANTE PARA OBTENER UNA DIFERENCIA DE FASE ENTRE LAS DOS SEÑALES, MEDIANTE LA CUAL, LA DIFERENCIA DE FASES ES DEMODULADA. UN CIRCUITO DETECTOR DE FASE DE TIPO DIGITAL EMITE LA SEÑAL DE DIFERENCIA DE FASE. EL CIRCUITO COMPARADOR DE FASE, COMPARA LAS SEÑALES DE REFERENCIA PLURALES, QUE OCASIONAN PREDETERMINADOS RETRASOS A LAS SEÑALES OSCILADAS LOCALMENTE QUE TENGAN FRECUENCIA PORTADORAS, CON SEÑALES MODULADAS INTRODUCIDAS. PREFERENTEMENTE, SE PRODUCE UNA SEÑAL PULSO CON UNA DIFERENCIA DE FASE ENTRE LA SEÑAL MODULADA INTRODUCIDA Y LA SEÑAL OSCILADA LOCALMENTE, Y LA AMPLITUD DEL PULSO DE ESTA SEÑAL DE PULSO ES MEDIDA POR UN CONTADOR. MEDIANTE LA DIGITALIZACION DE TODO EL COMPARADOR DE LA FASE, ES POSIBLE HACER UNA DEMODULACION CON BAJO CONSUMO ELECTRICO Y UN CIRCUITO DE SIMPLE CONSTRUCCION.
