楼主最好把作者，版次也写上，光看这个目录还以为是教材呢，下来才知道是潘裕友翻译的安捷伦公司的【Agilent _Spectrum Analysis Basics _Application Note 150】。不过还是谢谢楼主的分享。

靠，现在的比原来的网站差多了

顶一下，谢谢分享！

谢谢分享！

谢谢提供。。。

平时常常用到频谱,但至于是怎么一回事还真不知道

这个一定要顶起

很好的资料，谢谢分享。

谢谢楼主提供资料的分享！！

好东西，谢谢楼主！！

频谱分析，是射频测试的根本

好东东。。顶上。。。。:15bb:27bb

好东西，分享了{:7_1234:}

看了      确实不错
