基于FPGA的信号采集及其频谱显示

Acquisition of Signal and Display of Spectra Based on FPGA

介绍了一种基于FPGA信号的采集及其频谱的分析和显示方法。FPGA集成了A/DC控制驱动模块、FFT运算模块和VGA控制驱动模块。本设计的所有功能模块及子模块都使用Verilog HDL语言描述,具有自主知识产权。

A way to collect signal and display its spectra based on FPGA is introduced. All model such as A/ DC control model, FFT model and VGA control model have been integrated on FPGA. These units and sub-units were designed by Verilog HDL, so this designation has independent intellectual property.
