摘　　要：介绍了一种基于FPGA设计的数字化频谱分析技术。这里应用FPGA的设计方法，采用流水一与并行方式，尽量避免瓶颈的出现，提高系统时钟频率，达到高速处理，大大缩短数字信号的频谱分析时间。A way about digital spectral analysis based on FPGA is introduced in this paper. By applying FPGA design method, and using the serial and parallel architecture in the whole design, the bottleneck is avoided, the frequency of the system clock is increased and high—speed performance is achieved. Then the process time of digital spectral analysis is greatly decreased.
