Abstract

"MéTODO PARA USAR UM PROJETO DE AMOSTRAGEM SìNCRONA EM UM MODO DE AMOSTRAGEM DE TAXA FIXA". O presente pedido diz respeito no geral a aparelhos, tal como um aparelho de processamento de sinal de televisão, que processam sinais de radiofreq³ência. Mais especificamente, o presente pedido é particularmente útil em circuitos integrados que tenham que combinar conjunto de circuitos que opera em um modo de amostragem síncrona que tem que ser adaptado para uso com uma aplicação do modo de amostragem de taxa fixa. De acordo com uma modalidade exemplar, o aparelho de processamento de sinal 100 compreende uma fonte de um sinal digital de taxa fixa 220, um conjunto de circuitos de processamento de sinal 240 que opera em um modo de amostragem síncrona, em que o conjunto de circuitos de processamento de sinal 240 compreende um sinal representativo de uma taxa de símbolos, e um interpolador 230 para processar o sinal digital de taxa fixa para produzir amostras na taxa de símbolos.
