Abstract
"MéTODO E APARELHO PARA GERAR PULSOS A PARTIR DE FORMAS DE ONDA ANALóGICAS". São previstos um método e um aparelho para gerar pulsos de saída ou oscilações em resposta a formas de onda analógicas que envolvem excitar, com uma forma de onda analógica conhecida, mas arbitrária (210), um circuito (302) com um ponto de funcionamento variável e tendo uma função de transferência caracterizada por uma região de funcionamento instável limitada por uma primeira região de funcionamento estável e uma segunda região de funcionamento estável. A forma de onda analógica é caracterizada por ter uma primeira região de informação e uma segunda região de informação. Em resposta à detecção da primeira e da segunda regiões de informação, o ponto de funcionamento do circuito é forçado para dentro de suas regiões instável e estável. Isto produz uma seq³ência de comportamentos oscilatório e não-oscilatório na saída do circuito.
