摘要
针对"频率合成"课程的特点,笔者采用Simulink按实际电路组成搭建模块的方法,仿真实现了直接数字式频率合成器模块,在此模型上可进行电路工作特性的验证和电路级间信号的观察。还可以进行一些直接数字式频率合成的噪声性能分析和改进方法研究。实践证明,采用仿真实验的方法能够观察到一些硬件实验难以捕捉的现象,可以培养学生的参与意识,成为硬件实验的有效补充。
According to the characteristic of Frequency Synthesis course,a software direct digital frequency synthesizer is developed based on Simulink,which can be used to validate the circuit mechanism and observe the interstage process.Additional noise performance and improvement research can be carried on based on this model.It proves that this system can help the student to arouse enthusiasm,find more details,hence can be regarded as complement of real-circuit experiment.
