The text introduces the method of analysis and design of this measurements on the platform of digital oscillograph
本文即介绍了在数字示波器的平台上实现信号频谱分析的方法及设计。
But the bandwidth of the raw radar video is too wide to transmit directly in the common communication channel
但是雷达原始视频信号频谱很宽，要求传输设备有很宽的通频带，而且效率低、投资大。
In the digital intermediate frequency project , the intermediate frequency signal is converted to digital signal directly into the dsp chip , then it is be processed by dft
数字中频方案将中频信号直接通过a / d转换后送入dsp芯片进行dft变换，最后得到待测信号频谱的采样序列。
