Abstract
UN RECEPTOR SUPER-REGENERATIVO ELECTRICAMENTE SINTONIZADO (10) QUE CONSTA DE UN OSCILADOR TIPO REALIMENTACION QUE TIENE UNA SALIDA DE SEÑAL Y UNA ENTRADA DE SEÑAL Y COMPONENTES DE DESPLAZAMIENTO DE FASE (30) CONECTADOS EN UN BUCLE DE REALIMENTACION PARA EL ACOPLAMIENTO DE LA SALIDA DE SEÑAL A LA ENTRADA DE SEÑAL PARA PROVOCAR OSCILACIONES, Y UN OSCILADOR DE INTERRUPCION (35) ACOPLADO A LA ENTRADA DE SEÑAL PARA CONMUTAR EL OSCILADOR ENTRE UN MODO OSCILANTE Y OTRO NO OSCILANTE. HAY CONECTADO UN DISPOSITIVO DE CAPACITANCIA VARIABLE (40), COMO POR EJEMPLO UN DIODO TIPO VARACTOR, ENTRE LA SALIDA DE SEÑAL Y UN POTENCIAL DE REFERENCIA (21), Y UN MICROPROCESADOR (105) PROPORCIONA UNA TENSION DE SINTONIZACION (42) QUE ES APLICADA A LA SALIDA DE SEÑAL PARA VARIAR LA CORRIENTE EN EL DIODO TIPO VARACTOR, VARIANDO ASI LA FRECUENCIA DE TRABAJO CENTRAL DEL OSCILADOR. LA FRECUENCIA DE TRABAJO CENTRAL DEL OSCILADOR ES DETECTADA POR UN ANALIZADOR DE ESPECTRO (112) Y COMPARADA CON UNA FRECUENCIA DE TRABAJO CENTRAL DESEADA POR UN CONTROLADOR (118). EL CONTROLADOR CONTROLA A UN GENERADOR DE SEÑALES (123) PARA TRANSMITIR UNA SEÑAL DE CONTROL QUE ES RECIBIDA POR EL RECEPTOR Y SUMINISTRADA AL MICROPROCESADOR PARA VARIAR LA TENSION DE SINTONIZACION PARA CAMBIAR LA FRECUENCIA DE TRABAJO CENTRAL DEL OSCILADOR PARA QUE SEA IGUAL A LA FRECUENCIA DE TRABAJO CENTRAL DESEADA. HAY UNA EEPROM (108) PARA ALMACENAR LA TENSION DE SINTONIZACION REQUERIDA PARA PRODUCIR OSCILACIONES EN LA FRECUENCIA DE TRABAJO CENTRAL DESEADA.
