Abstract

"MéTODO DE MONITORAçãO DE UM EVENTO MICROSSìSMICO". Um método de monitoração de um evento microssísmico compreende a detecção do referido evento para a produção de um primeiro sinal dependente do referido evento, o primeiro sinal incluindo um ruído a uma freq³ência de f Hz (por exemplo, 50 Hz); a tomada de uma primeira amostra do primeiro sinal; a tomada de uma segunda amostra do primeiro sinal, a segunda amostra ocorrendo n/f segundos após a primeira amostra, onde n é um inteiro (por exemplo, 1); e a subtração da primeira e da segunda amostras uma da outra para a produção de um outro sinal dependente do evento, no qual o ruído foi pelo menos parcialmente compensado.
