Abstract
0CONTROLADOR E SISTEMA DE COMUTAçãO DE AMPLIFICADOR" Trata-se de um controlador de comutação de amplificador que é proporcionado para uso em um sistema de transmissão de extremo de entrada tendo primeiro e segundo amplificadores e trajetórias de entrada e saída do amplificador conectadas a um dentre primeiro e segundo amplificadores, que se torna o amplificador correntemente ativado. O controlador de comutação de amplificador compreende um amostrador de entrada para fazer amostra de um sinal combinado na trajetória de sinal de entrada e medir um nível de sinal de entrada. O controlador de comutação de amplificador também compreende um amostrador de saída para fazer amostra do sinal combinado amplificado na trajetória de sinal de saída e medir um nívelo de saída. Um meio de programa recebe os níveis de sinal de entrada e de saída e determina se o amplificador correntemente ativado não está funcionando de modo apropriado. se ele não estiver funcionado apropriadamente, o meio de programa gera um sinal de controle para um comutador. Em resposta aos sinais de controle, o comutador desconecta as trajetórias de sinal de entrada e de saída do amplificador correntemente ativado e conecta cada uma das trajetórias de sinal de entrada e de saída ao outro dentre o primeiro e segundo amplificadores.
