Abstract

resumo “sistemas e métodos para realizar um rastreamento de fase dentro de um sintonizador com base em adc” os sistemas e métodos para realizar um esquema de rastreamento de fase para um sintonizador com base em um conversor analógico para um digital. em muitas modalidades, um esquema de rastreamento é usado em que inclui um circuito fechado em fase que corrige a fase dos sinais de saídas e um compensador de modulação de amplitude que modula a amplitude dos sinais digitais de saída para compensar o ruído de fase com base nos sinais digitais de saída recebidos.
