Abstract

"MéTODO E SISTEMA PARA DIGITALIZAçãO DE RF DE MúLTIPLOS CANAIS COM SELETIVIDADE ANALóGICA". Um sistema (10) e método (100) para digitalizar uma banda completa de canais de RF para permitir o processamento simultâneo de mais de um canal. Múltiplos filtros de passagem de banda sintonizáveis (14) são utilizados para os canais em particular a serem processados. As saídas de filtro são combinadas (16) para formar um sinal para digitalização (18). Em outra modalidade, um sinal indesejado é rejeitado (112) para fornecer mais energia disponível para uma recepção de um sinal desejado.
