Abstract

SISTEMA, E MéTODO A presente invenção proporciona sistemas e métodos para pré-filtro (28) em um receptor de VHF utilizando filtros de Sistemas Micro-Eletro-Mecânicos (MEMS) O sistema inclui uma antena (24), e primeiro, e segundo filtros de Sistemas Micro-Eletro-Mecânicos (28). O primeiro filtro de MEMS filtra um sinal recebido pela antena com base em uma primeira largura de faixa predefinida, e o segundo filtro de MEMS filtra o sinal filtrado pelo primeiro filtro de MEMS com base em uma segunda largura de faixa, O sistema também inclui um conversor de analógico para digital (32) que converte o sinal filtrado pelo segundo filtro de MEMS na forma de um sinal digital, um conversor de rebaixamento (34) que converte para baixo o sinal produzido pelo conversor A a D, e um processador de e) sinal digital (40) que processa o sinal digital convertido para baixo produzido pelo conversor de rebaixamento. O primeiro e segundo filtros de MEMS ou o conversor de rebaixamento são ajustáveis com base em um sinal de sintonia recebido.
