Abstract

UN CIRCUITO DE CONTROL AUTOMATICO DE GANANCIA EN BUCLE CERRADO (AGC) CON MARGENES DE FUNCIONAMIENTO DE ALTA GAMA DINAMICA QUE TIENE UN CIRCUITO AMPLIFICADOR (18) PARA RECIBIR UNA SEÑAL DE ENTRADA, EN DONDE LA POTENCIA DE LA SEÑAL PUEDE VARIAR, Y UNA SEÑAL DE CONTROL. EL CIRCUITO AMPLIFICADOR (18) RESPONDE A LA SEÑAL DE CONTROL PARA AMPLIFICAR LA SEÑAL DE ENTRADA A UN NIVEL DE GANANCIA CORRESPONDIENTE A LA SEÑAL DE CONTROL PARA ASI PROPORCIONAR UNA SEÑAL DE SALIDA CORRESPONDIENTE. HAY ACOPLADO UN CIRCUITO DE MEDICION (20) A LOS ELEMENTOS DE AMPLIFICACION (18) PARA MEDIR LA POTENCIA DE LA SEÑAL LOGARITMICA DE LA SEÑAL DE ENTRADA AMPLIFICADA Y PROPORCIONAR LA SEÑAL DE MEDIDA LINEAL CORRESPONDIENTE. HAY TAMBIEN UN CIRCUITO DE INTEGRACION (22) PARA RECIBIR LA SEÑAL DE MEDIDA Y UNA SEÑAL DE REFERENCIA QUE CORRESPONDE A UNA POTENCIA DE SEÑAL DESEADA DE LA SEÑAL DE SALIDA. EL CIRCUITO DE INTEGRACION (22) INTEGRA, EN RELACION AL TIEMPO, LA DIFERENCIA ENTRE LA SEÑAL DE MEDIDA Y LA SEÑAL DE REFERENCIAY GENERA LA SEÑAL DE CONTROL CORRESPONDIENTE AL RESULTADO DE LA INTEGRACION.
