Abstract

DISPOSITIVO DE CODIFICAçãO, DISPOSITIVO DE DECODIFICAçãO E MéTODO DO MESMO. A presente invenção refere-se a um dispositivo de codificação capaz de ajustar, apropriadamente, a faixa dinâmica de espectro inserido de acordo com a técnica para a substituição de um espectro de uma certa banda com um espectro de outra banda. O dispositivo inclui uma unidade de modificação de espectro (112), que modifica um primeiro espectro S1(k) da banda O "= k < FL de várias maneiras, para mudar a faixa dinâmica de modo que uma maneira de modificação para obtenção de uma faixa dinâmica apropriada é verificada. A informação referente á modificação é codificada e fornecida para uma unidade de multiplexação (115). Através do uso de um segundo espectro S2(k), tendo uma banda de sinal válida O "= k.
