but when it comes to a collaborative learning experience the one thing a book is is closed. In terms of platforms, I want something simple, accessible, sharable and open. Something like Google Drive. Wait, not just like Google Drive, but maybe Google Drive itself, because there’s nothing...
I don’t believe Laurent got to upper intermediate level with the frame of mind Dellar attributes to him, I don’t believe he said or thought that English and French grammars are the same; and I don’t believe he said the words Dellar attributes to him. It’s interesting that Dellar ...
I thought it would be excellent for use in the classroom, if you can’t find a way to use the whole book (definitely accessible for learners from upper intermediate and above, possibly intermediate). Let me describe my house. It was built within the last forty years and is a simple ...

AM模块和Base band模块配合使用能进行幅度调制实验,可用频谱仪GSP-730来观察测量调幅波的特性。本实验系统可通过USB接口和电脑通讯,可用指令控制电路的开闭,组成通讯纠错实验项目。学生能透过各种实验现象探究其本质,加深学生对射频电路各个部分的理解,这就好比化整为零,各个击破,达到把理论知识细化的目的。本实验系统...
Base band模块能够模拟产生基带信号,可提供Sine波、Square波、Triangle波三种波形,输出频率和幅度可调。实验过程中三种波形可以任意切换,以便满足不同实验对不同信号的要求。RF Synthesizer/FM模块是一个射频综合器用于产生频率可调的载波信号,同时也可以起到频率调制的作用。这个模块可以说是射频电路学习中的重点,这部分...
