摘要
介绍了计算机控制的数字立体声调频发射机的设计。该系统利用DSP实现数字立体声调制,并通过AD9852 DDS芯片将数字信号转换成射频信号。系统采用计算机控制,接收S/PDIF接口的数字音频输出,适合校园数字调频广播和外语听力训练。
A design of digital stereo frequency modulation transmitter system based on DSP and DDS is described. The digital stereo modulation is implemented by DSP, and the digital signal is transformed to RF signal by AD9852. The system is controlled by computer, and accepts the digital audio from S/PDIF. It is suitable for digital FM broadcasting in campus and listening training for foreign language study.
