Abstract

RECEPTOR DE CIRCUITO DE VIA CONTROLADO EN FASE. CONSTA DE UN PRIMER DETECTOR SINCRONO SEGUIDO POR UN CIRCUITO DE EVALUACION DE AMPLITUD QUE CONTIENE UN CONMUTADOR DE UMBRAL; DE UN CIRCUITO DE CONTROL DE FASE AUTOMATICO QUE MANTIENE UNA RELACION DE FASE DADA ENTRE LA TENSION AC RECIBIDA Y UNA TENSION AC DE REFERENCIA, APLICADA AL DETECTOR SINCRONO Y NECESARIA PARA LA DETECCION SINCRONA; DE UN SEGUNDO DETECTOR SINCRONO (SD2) AL QUE SE PRESENTA UNA SEÑAL DE REFERENCIA EN CUADRATURA CON LA TENSION DE REFERENCIA AC; Y DE UN CIRCUITO DE CONTROL DE FRECUENCIA QUE VARIA LA FRECUENCIA DE LA TENSION DE REFERENCIA AC DE ACUERDO CON LA SEÑAL DE SALIDA DEL SEGUNDO DETECTOR SINCRONO (SD2).
