摘要
介绍基于DDS的信号发生器工作原理和设计过程,并对关键模块及外围电路进行了仿真和误差分析。经功能验证和分析测试,达到了预定的各项技术指标。旨在建立一种以FPGA为核心,功能可裁剪、波形任意调整的高性能信号发生器设计方法。采用该设计法将有效地降低开发成本,提高设计效率,并具有一定的工程指导意义和实用价值。
The signal generator's work principle and design methods based on DDS technology are introduced, and it also the error for key modules is analysed and peripheral circuits are simulated. By functional verification and testing analysis, the signal generator design has achieved the predetermined technical specifications. Aiming to establish a design method for the high performance and cut - function arbitary waveform generator taking FPGA as design core. This method is helpful in saving the development cost and enhancement efficiency of the design,and it also has certain project guiding sense and practical value.
