Abstract

Схема автоматической регулировки усиления, включающая в себя усилитель (11) с переменным усилением, выполненный с возможностью принимать принимаемый сигнал (R) и выводить усиленный сигнал (А) в аналогово-цифровой преобразователь (20), и контроллер (12) усиления, который соединен с упомянутым усилителем (11) с переменным усилением для приема упомянутого усиленного сигнала (А) и для управления усилением упомянутого усилителя (11) с переменным усилением. Контроллер (12) усиления выполнен с возможностью определения возникновения порогового события каждый раз, когда усиленный сигнал (А) достигает заданного порогового значения, уменьшения усиления усилителя (11) с переменным усилением при каждом возникновении порогового события, измерения задержки после последнего порогового события, увеличения усиления усилителя (11) с переменным усилением, если задержка больше, чем заданное значение задержки, и если усиление усилителя (11) с переменным усилением не равно максимуму.
