Abstract

"MéTODO E SISTEMA PARA PROCESSAMENTO DE SINAL DE DIAGNóSTICO". é descrito um utilitário de processamento de sinais envolvendo transformadas de domínio de tempo para freq³ência para aplicações que incluem o processamento de sinais de diagnóstico médico. Tais transformadas podem ser usadas para definir uma função de densidade espectral contínua ou outra função de densidade espectral, incluindo valores diferentes de zero em intervalos de freq³ência irregularmente espaçados. A invenção, desse modo, permite a representação mais acurada de certos espectros reais e alargamento espectral reduzido. O utilitário também compensa erros de digitalização associados à conversão analógico para digital. A invenção apresenta vantagens particulares em relação a contextos médicos, em que o sinal recebido possui um conteúdo espectral mutável como resultado de uma interação de um sinal interrogador com materiais fisiológicos em movimento, tais como o sangue fluindo através de uma artéria.
