摘要
Abstract
This paper introduces a signal acquisition and spectrum analysis system based on FPGA.First the system is divided into several modules,and then the key design points of each module are given,and the Analog to Digital Change（A/DC） module,the Fast Fourier Transform（FFT） module,the memory module and the Video Graphics Array（VGA） module are designed.Lastly both functional simulation and timing simulation are completed so that the design of these modules is validated.According to the experiment,the implement can realize the signal acquisition,spectrum analysis and display functions.The system is stable and reliable.关键词
