Abstract
Patente de Invenção: <B>"FILTRO DE PASSAGEM ALTA DE IMITAçãO EM UM RELé DE PROTEçãO"<D>. Um filtro de imitação o qual pode ser implementado em um circuito analógico ou digital, e o qual remove o deslocamento de cc ou outro ruído de um sinal de entrada utilizando uma técnica de pseudodiferenciação. O sinal de entrada é ajustado por um valor de retorno, e o sinal ajustado é amplificado por um fator de ganho proporcional para gerar um sinal de saída. O valor de retorno é determinado pela integração do sinal de saída e pela multiplicação da integração por um fator de ganho de integração. O filtro de imitação evita a geração de falsos picos de sinal.
