Abstract

dispositivo de filtro. a invenção refere-se a um dispositivo de filtro para filtrar um sinal de entrada, o sinal de entrada compreendendo um sinal de relógio tendo uma frequência de relógio. o dispositivo de filtro compreende um filtro (101) para filtrar o sinal de entrada com um primeiro conjunto de coeficientes de filtro para obter um primeiro sinal filtrado, e para filtrar o sinal de entrada com um segundo conjunto de coeficientes para obter um segundo sinal filtrado, um correlacionador de domínio de frequência (103) para correlacionar um primeiro subconjunto de componentes de domínio de frequência do primeiro sinal filtrado para obter um primeiro valor de correlação, e para correlacionar um segundo subconjunto de componentes de domínio de frequência do segundo sinal filtrado para obter um segundo valor de correlação, em que o primeiro subconjunto de componentes de domínio de frequência correlacionado e o segundo subconjunto de componentes de domínio de frequência correlacionado são respectivamente localizadas dentro de uma faixa predeterminada dos sinais correlacionados compreendendo a frequência de relógio, e um processador (105) para selecionar quer o primeiro conjunto de coeficientes de filtro ou o segundo conjunto de correlação e o segundo valor de correlação para filtrar o sinal de entrada.
