Abstract
"PROCESSOS E APARELHOS PARA REDUZIR ESPALHAMENTO EM UM SINAL DIGITAL DE ENTRADA QUE INCLUI UMA PRIMEIRA SEQUêNCIA DE VALORES DE AMOSTRA, E, PARA PROCESSAR INFORMAçãO DE SINAL ACúSTICO". Espalhamento é reduzido em um sinal digital de entrada (A) que inclui uma primeira seq³ência de valores de amostra. Um sinal digital de saída (B) é produzido em resposta ao sinal digital de entrada. O sinal digital de saída inclui uma segunda seq³ência de valores de amostra, em que segunda seq³ência de valores de amostra tem uma densidade maior de valores de amostra não zero do que a primeira seq³ência de valores de amostra.
