摘要
Quartus环境以FPGA为数字电路和存储体载体,运用DDS技术虚拟实现任意信号产生,并在信号低频段仍能保持恒定很高的频率相对精度。本文重点介绍其系统设计原理、恒定精度分析、FP GA设计及实验结果。
A virtual arbitrary waveform generator in DDS is introduced,in which FPGA is used for the digital circuits and memory carriers in Quartus,the constant high relative frequency precision can be realized in the low frequency area.The design principle of the system,the analysis of constant precision,FPGA design and experimental results are focused in the paper.
