Abstract

"SISTEMA E MéTODO PARA A DETECçãO E REMOçãO DE RUìDO DE RADIOFREQuêNCIA DE ARTEFACTOS EM RELAçãO A SINAIS DE BIOPOTENCIAIS". A presente invenção refere-se a um sistema e método de identificação e remoção de ruído de radiofreq³ência de artefato a partir de biopotenciais identifica épocas contaminadas com ruído de radiofreq³ência. As épocas contaminadas são então substituídas com épocas recentes não contaminadas armazenadas em uma memória intermediária, na dependência do nível de artefato atual e da disponibilidade de dados adequados. Descontinuidades que se apresentam no início das épocas substituídas são ajustadas por meio de uma função de seleção de janela.
