Abstract

"DISPOSIçãO PARA O RECONHECIMENTO DE FALHAS EM UMA INSTALAçãO DE AVALIAçãO DE SINAL DIGITAL". é descrita uma disposição para a avaliação de sinais, sobretudo para o reconhecimento de batimentos em uma máquina de combustão interna, na qual os sinais fornecidos pelos sensores são avaliados de forma digital e que é realizado um reconhecimento de falha que realiza duas funções de teste distintas, sendo que uma primeira função de teste aplica um pulso de teste em um ponto predeterminável e a segunda função de teste desliga os sinais dos sensores e supervisiona cada reação da parte de circuito analógico e digital.
