本章介绍二端口(网络)及其方程,二端口的YZ、A、H等参数矩阵以及它们之间的相互关系,还介绍转移函数,型和Ⅱ型等效电路及二端口的连接,最后介绍回转器和负阻抗变换器

Overview: A good 'H NMR sample contains about 10 mg of compound. The solution should contain no solids or paramagnetic impurities. Your deuterated NMR solvent should be free of water,and your NMR spectrum should contain no solvent peaks. Reference: Zubrick page 295 is relatively useful, but you should follow the specifics in this handout Also, keep in mind that we won't be running continuous wave spectrometers, so you should disregard any discussion of them.

一、简答题: (1)在理想信道下的最佳基带系统中,发送滤波器Gr(),接收滤波器()和系统总的传 输函数H()之间应满足什么关系?

We define transfer function H(s) as a ratio of the Laplace transform of system output (or response)(s) to the Laplace transform of the input(or forcing function)v(s) when all initial conditions are zero, then
