Abstract

"DISPOSITIVO DE MODULAçãO SIGMA-DELTA PARA MODULAR UM SINAL DE ENTRADA PARA OBTER UM SINAL DE SAìDA, MéTODO PARA MODULAçãO SIGMA-DELTA DE UM SINAL DE ENTRADA PARA OBTER UM SINAL DE SAìDA, E, APARELHO PROCESSADOR DE SINAL". Modulação sigma-delta é provida, compreendendo suprir um sinal de entrada a um primeiro SDM, subtrair a saída do primeiro modulador sigma-delta do sinal de entrada, filtrar a saída do subtrator para obter um sinal filtrado, retardar o sinal de entrada, adicionar o sinal filtrado ao sinal de entrada, suprir a saída do adicionador a um segundo SDM, e prover a saída do segundo SDM. O primeiro SDM, em combinação com a subtração e filtragem, despacha um sinal de correção que, por sua adição ao sinal de entrada, reduz a distorção no segundo SDM, cujo segundo SDM efetua, de fato, a modulação sigma-delta do dispositivo.
