2年前,我紧张地选择了X-paramter类,并没有太多时间使用它们。
我现在再次查看它,试图理解数据文件。 我理解光谱成像的概念给出T项与S项。 但是,在课堂上(Xp2实验室),“实际上,当小信号出现在与大信号和/或其谐波相同的频率上时,我们对系统的响应感兴趣。” 我的问题是,如果小信号出现在与大信号相同的频率上,我们如何得到S和T项 - 响应不会直接落在大信号/谐波上?编辑:lcormier on Mar 15,2013 8:01 AM 以上来自于谷歌翻译 以下为原文 I took the X-paramter class nerly 2 years ago, and have not had much time using them. I am now looking at it again, trying to understand the data file. I understand the concept of spectral imaging giving the T terms vs the S terms. But, in the classs ( Xp2 Lab), "In reality, we are interested in the response of the system when the small-signal occurs on the same frequency as the large-signal and/or its hARMonics." My question is, if the small-signal occurs on the same frequency as the large-signal, how do we get S and T terms - won't the response fall directly on the large-signal/harmonics?

是的,但通过改变prope-tone阶段的值,我们可以得到一组超定的方程,允许我们破解S和T项。
以上来自于谷歌翻译 以下为原文 Yes, but by changing the value of the prope-tone phase, we can get an overdetermined set of equations that allows us to crack out the S and T terms. |
