Abstract

CIRCUITO DIGITAL DE CONTROL AUTOMATICO DE GANANCIA. EL CIRCUITO TIENE DOS BUCLES DE CONTROL AUTOMATICO DE GANANCIA QUE SE ACTIVAN ALTERNATIVAMENTE. EL PRIMERO DE ELLOS (11) ES DEL TIPO DE ALIMENTACION EN AVANCE, SE ACTIVA CUANDO SE SUMINISTRA INICIALMENTE UNA ENTRADA Y PRODUCE UN FACTOR DE PONDERACION PARA MANTENER CONSTANTE EL NIVEL DE SALIDA DE CONTROL AUTOMATICO DE GANANCIA. EL SEGUNDO BUCLE (12) ES DEL TIPO DE REALIMENTACION, Y FUNCIONA A PARTIR DE UN VALOR PREAJUSTADO, POR SU PROPIO FILTRO DE PASO BAJO, DEL COEFICIENTE DE PONDERACION PRODUCIDO POR EL PRIMER BUCLE.
