Abstract
FILTRO CONFIGURáVEL PARA PROCESSAR SINAIS DE áUDIO DE TELEVISãO Um codificador de sinal de áudio de televisão inclui uma matriz que soma um sinal de áudio de canal esquerdo e um sinal de áudio de canal direito para produzir um sinal de soma. A matriz também subtrai um dos sinais de áudio da esquerda e da direita do outro para produzir um sinal de diferença. O codificador também inclui um filtro digital de resposta a impulso infinito que seletivamente usa um ou mais conjuntos de coeficientes de filtro para filtrar o sinal de diferença. Cada conjunto selecionável de coeficientes de filtro está associado a uma aplicação de filtragem única para preparar o sinal de diferença para transmissão.
