摘要
给出一种基于DSP的数字调制器实验模块设计,包括DSP实现直接数字频率合成(DDS)系统,在DDS基础上实现8种数字调制方法。实测结果表明,该实验模块达到预期目标,非常适合学生用于DSP、DDS和数字调制原理的学习和进一步开发。
An experimental digital modulator module based on digital signal processing (DSP) has been designed. After implementation of the direct digital frequency synthesis (DDS) system on DSP, the signal can be modulated in 8 modes. The test results indicate that the module reaches the desired performance and can be used successfully to help students learn DSP, DDS and the principles of digital modulation experiments. Furthermore, the system can also be developed on existing platforms.
