摘要
以FPGA为核心,根据DDS原理设计数控信号源,采用VHDL语言实现各功能模块。该信号源可输出正弦波、方波和三角波,输出信号的频率以数控方式调节,幅度连续可调。与传统信号源相比,该信号源具有波形质量好、精度高、设计方案简洁、易于实现、便于扩展与维护的特点。
The paper introduces the design of the digital control signal source based on FPGA and DDS technology.Each functional module is designed with VHDL.The design can output sine wave,quadrate wave and trigonal wave.The frequency of each wave can be adjusted by the digital control method.This signal source has the advantages over the traditional signal source of better quality,higher precision,simple design,and easy implementation,extension and maintenance.
