摘要
介绍了频谱分析仪中视频检波的几种常用方式,给出了如何利用FPGA来实现正峰值、负峰值、取样和ROSENFELL视频检波的原理方法;论述了在实际工程中如何应用数字视频检波并给出了不同视频检波方式的实验结果。
This article mainly introduced several general methods of video demodulation in spectrum analyzer. The principles of the digital integration video demodulation, as well as the principle of how to realize peak value, negative value, sample and ROSENFELL video demodulation with FP GA, were presented. How to use digital video demodulation in project was also discussed. Finally, we gave the experimental result in various pattern of video demodulation.
