Abstract

CIRCUITO ELETRÈNICO, E, MéTODO PARA AJUSTAR PELO MENOS UMA PROPRIEDADE DE UM SINAL DE ENTRADA DE UM ELEMENTO NãO LINEAR A invenção diz respeito a um circuito eletrónico para ajustar pelo menos uma propriedade de um sinal de entrada de um elemento não linear. Um detector detecta a intensidade do sinal de entrada. Um controlador analógico forma pelo menos um sinal de controle como uma aproximação por parte de uma dependência não linear entre o pelo menos uma propriedade e a intensidade do sinal de entrada detectado pelo detector. Um circuito de ajuste ajusta pelo menos uma propriedade do sinal de entrada de acordo com o pelo menos um sinal de controle proveniente de pelo menos um controlador.
