Abstract

UN METODO PARA CALIBRAR UN PARAMETRO DE UN AMPLIFICADOR DE UNA PLURALIDAD DE CANALES, QUE COMPRENDE MEDIR CADA SALIDA EN CADA AMPLIFICADOR A UNA PLURALIDAD CORRESPONDIENTE DE VALORES DE CONTROL DE GANANCIA Y A UN NIVEL CORRESPONDIENTE DE SEÑAL DE ENTRADA A CADA AMPLIFICADOR; COMPUTAR LA GANANCIA DE CADA AMPLIFICADOR EN LA OPERACION DE MEDIDA; COMPUTAR LUEGO LAS CONSTANTES DE CONTROL DE GANANCIA EN CADA AMPLIFICADOR; Y APLICAR A CADA AMPLIFICADOR UNA SEÑAL DE CONTROL DE GANANCIA CAMBIADA CORRESPONDIENTE PARA AJUSTAR LA GANANCIA CORRESPONDIENTE A UN VALOR CALIBRADO PREDETERMINADO. EL INVENTO SE APLICA PARTICULARMENTE EN CIRCUITOS ANALOGICOS DE RADARES.
