Abstract

"SISTEMA DE PESQUISA DE DESLOCAMENTO LNB PARA PRODUTOS DBS" A presente invenção diz respeito a um aparelho de sintonização de sinal digital (9) que inclui um sistema de correção de freq³ência de deslocamento (919). No sistema de correção de freq³ência de deslocamento, a pesquisa por um sinal de deslocamento começa a partir de um ponto final de uma banda de freq³ências no qual o sinal de deslocamento pode ser encontrado.
