摘要

多年来，模拟信号处理一直主导着汽车收音机的设计。如果在汽车收音机中使用数字信号处理，则从多路信号(音频)开始，其中滤波和声音控制为收音机提供了新的功能。双芯片数字汽车收音机的概念超越了这些特征:中频(IF)的数字化;以及采用嵌入式DSP协处理器的混合信号处理技术。

A two-chip digital car radio

Car radio design has been dominated for years by analog signal processing. If digital signal processing is used in a car radio, it begins with the multiplex signal (audio frequency) where filtering and sound control gives new features to the radio. The concept of the two chip digital car radio goes beyond these features: digitization of the intermediate frequency (IF); and mixed-signal processing technology using embedded DSP coprocessors.
