Abstract
"CONTROLE DE GANHO PARA DISPOSITIVO DE COMUNICAçõES". A presente invenção apresenta sistemas e técnicas para controle de ganho que inclui amplificação de um sinal com um amplificador que possui um ganho representado por uma dentre uma pluralidade de curvas de ganho que dependem de um valor de um parâmetro, o sinal sendo amplificado em um primeiro dos valores de parâmetro; e controle do ganho do sinal amplificado a partir de uma curva de ganho predeterminada que relaciona a curva de ganho do amplificador a um segundo dos valores de parâmetro mediante ajuste de um sinal de controle de ganho que corresponde a um ponto na curva de ganho predeterminada como uma função do primeiro dos valores de parâmetro, e aplicar o sinal de controle de ganho ajustado ao amplificador. é enfatizado que este resumo é provido para cumprir com as regras que requerem um resumo que permitirá a um buscador ou outro leitor, encontrar rapidamente o assunto da pesquisa técnica.
