Abstract

"DISPOSITIVO PARA REMOVER SINAL DE INTERFERêNCIA COM CARACTERìSTICA DIFERENTE E MéTODO PARA REMOçãO DO MESMO". A presente invenção refere-se a um dispositivo para remover um sinal de interferência com uma característica diferente incluído em sinais de entrada, e um método para remoção de sinal de interferência que são descritos. O dispositivo para remover um sinal de interferência compreende um filtro supressor de banda (notch filter) IIR para gerar um entalhe (notch), para remover o sinal com uma característica diferente incluído nos sinais de entrada, uma unidade de rastreio de freq³ência para rastrear uma freq³ência no domínio de freq³ência para o sinal com uma característica diferente incluído nos sinais de entrada, a fim de fornecer um valor de posição do entalhe (notch), e uma unidade de cálculo de relação de potência para calcular uma relação de potência do sinal diferente dos sinais de entrada na característica e fornecer um valor de profundidade do entalhe (notch) fixado em correspondência com a relação de potência calculada, em que o filtro supressor de banda (notch filter) IIR remove o sinal com uma característica diferente usando o valor de posição e o valor de profundidade. Conseq³entemente, o sinal com uma característica diferente incluído em sinais de entrada pode ser corretamente removido.
