Abstract
"APARATO E MéTODO PARA A CONVERSãO EM UMA REPRESENTAçãO TRANSFORMADA OU PARA A CONVERSãO INVERSA DA REPRESENTAçãO TRANSFORMADA". Para conversão de um primeiro e um segundo blocos de valores discretos em uma representação transformada, o primeiro bloco é transformado (102) de acordo com uma primeira regra de transformação e em seguida arredondado (104). Em seguida, os valores transformados arredondados são somados com o segundo bloco de valores discretos originais (106), para então processar (108) a soma resultante de acordo com uma segunda regra de transformação. os valores de saída da transformação através da segunda regra de transformação são novamente arredondados (110) e em seguida subtraídos (112) dos valores discretos originais do primeiro bloco de valores discretos para se obter um bloco de valores de saída inteiros da representação transformada. Através desse esquema de elevação multidimensional é obtida uma transformação inteira sem perdas, a qual pode ser revertida através da aplicação da mesma regra de transformação, mas com um sinal diferente na soma e na subtração, respectivamente, de modo que se possa obter também uma transformação inteira inversa. Comparada com uma separação da transformação em rotações, por um lado, obtém-se uma complexidade de computação significativamente reduzida e, por outro lado, evita-se um acúmulo de erros de aproximação.
