摘要
设计制作了的数字式频谱分析仪,被测信号经过A/D采集后,在FPGA内部完成DFT的实部和虚部的计算,以Nios II CPU为核心控制器件。系统运行稳定,功能相对齐全,人机界面友好。
The digital spectrum analyzer is designed.After sampling of the measured signal by A/D transfering,the FPGA is used to deal with all of the operations in real and imaginary parts of DFT,taking the Nios II CPU as the core control appliance.The operation of the system is stable,the functions are relatively good,and the man-machine interface is friendly.
