摘要
在广播系统的立体声数字调频激励器中,输入的音频信号可是数字或模拟信号。其中,数字信号常采用AES/EBU信号。介绍了一种基于DSP和CS8416的AES/EBU解码的设计方案。该方案电路结构简单,使用方便,适用于立体声数字激励器等设备的设计中。同时给出了AES/EBU解码系统的硬件电路和DSP中McBSP软件设置方案。
In digital FM exciter of broadcast system, digital audio signal and analog audio signal can be both used as input audio signal and digital audio signal usually uses AES/EBU standard. A design of AES/EBU decoding based on DSP and CS8416 is introduced. Because of simple circuit structure, this design fits for audio equipment design. The hardware and software design of AES/EBU are described.
