摘要
利用Altera公司的EP2C8Q208为控制核心,以TLV5618为DA转换芯片,运用DDS基本原理,通过Quartus II和ModelSim软件编写波形发生器的每个单元模块和测试模块,利用数码管显示波形的种类和频率值,利用按键步进控制波形的频率大小,系统产生的8种波形包括4种常规波形、3种常见调制波形以及任意波形。实验表明,采用该设计系统稳定性高,可扩展性强,波形可以任意调整,降低了设计的成本。
The design used Altera EP2C8Q208 as the core chip and TLV5618 as the DAC chip. By using DDS basic principle,each unit of the waveform generator module and test module are prepared by the Quartus II and ModelSim software,digital tube displayed waveform and frequency value, used a key to step control the size of the frequency of the waveform, eight kinds of waveform generated by the system include four conventional waveform, three common modulation waveforms and arbitrary waveforms. The experiment showed that the stability and the scalability of the system was well,and the waveform can be adjusted to reduce the cost of the design.
