摘　　要：基于数字频率合成技术,生成数字化正弦波,采用模块化设计和查表的方法实现。直接数字合成技术是一种先进的电路结构,能在全数字下对输出信号频率进行输出,在精度、灵活性上大大超越了模拟信号发生器。在Quartus II环境下,用超高速集成电路硬件描述语言编程,进行模块化设计。使用ALTERA公司提供的EP1K30TC144-3芯片作为核心器件进行设计,来实时生成数字化波形,结合GW48-CK实验开发系统,最终给出了信号发生器的设计方案。Based on the digital frequency synthesis technology,the digital sine wave is generated by modular design and look -up table method.The direct digital frequency synthesis technology,as a kind of advanced circuit structure,can output in full digital signal frequency.So it is much better than the analog signal generator in precision and flexibility.In the circumstances,Quartus II,with very -high -speed integrated circuit hardware description language,the modular design is conducted by programming. EP1 K30TC1 44 -3 chip from ALTERA,as the core component,is used for microchip design to generate digital wave in real -time.Combining with the experiment development system GW48 -CK,the signal generator design scheme is finally provided.
