It is my great honour to attend the speech of the world famous inspirator John Coutis. And the topic is"Never say no to yourself".

今天我听了世界著名激励大师约翰库缇斯主题为“别对自己说不可能”的演讲。

Each of them is composed of high frequency amplifier, intermediate frequency amplifier and sampling, digital phase uprightness intersector, DDS and the S band signal inspirator for the transmitter.

接收机的每个通道都由高频放大器、中频放大、中频采样、数字正交器组成，另外还有DDS信号产生和频率激励源用来形成雷达发射机所需的S波段脉冲调制激励信号。
