Abstract

DISPOSITIVO E MéTODO PARA O PROCESSAMENTO DE UM SINAL TENDO UMA SEQüêNCIA DE VALORES DISCRETOS". Ao processar um sinal tendo uma seqüência de valores discretos, onde há uma primeira faixa de freqüência na qual o sinal tem alta energia e onde há uma segunda faixa de freqüência na qual o sinal possui baixa energia, a seqüência de valores discretos é primeiramente manipulada (202) para obter uma seqüência de valores manipulados, de modo que pelo menos um dos valores manipulados seja um número não inteiro. Então, a seqüência de valores manipulados é arredondada (204) para obter uma seqüência de valores manipulados. O arredondamento é formado para realizar um formato espectral de um erro de arredondamento gerado de modo que um erro de arredondamento espectralmente formado tenha maior energia na primeira faixa de freqüência do que na segunda faixa de freqüência. Formando espectralmente o erro de arredondamento de modo que o erro de arredondamento não tenha qualquer energia nas áreas de armazenamento onde não há energia de sinal, uma codificação especialmente eficiente é obtida particularmente na conexão com um contexto de codificação sem perdas.
