打信号

The course is divided into two parts: Part 1: Signal representations - discrete and continuous; System representations; Linear time invariant systems (Superposition, Causality, Impulse response, Stability, Transfer functions); Discrete and continuous convolution.

通过 本课程的学习，学生应能掌握信号分析与线性系统的基本理论及分析方法，应能建立简单电路与系统的数学模型，并对数学模型求解，为后续课程的学习打好基础。

The use of mobile phone signal isolator, can be automatically designated to form the framework of an effective s你好eld to block mobile phone signals in the magnetic field, edsun-2010 mobile phone signal blocking s你好elding device is 10-40 meters in diameter in the range of effective to make GSM / DCS / CDMA / PHS mobile phone models, such as in你好bitory signals to the space to block the effects of mobile phone signals, so that can not be made and answered the phone, but do not affect the space outside the normal mobile phone signal transmission, leaving the MDPB set up mobile phone signal jammer-type space, the phone signal will not be interference, isolation, be able to resume normal use.

施用型手机信号断绝器，能在指定的规模内AUTO形成能够有用阻断手机信号的屏蔽磁力场，edsun-2010型手机信号阻断器的屏蔽直径是10-40米规模，在该规模内有用使GSM/DCS/CDMA/PHS等型号的手机信号被按捺，到达该空间内手机信号阻断的效验，使手机无法打出以及接听，但又不影响该空间之外的手机信号的正常传道输送，离开设置有MDPB型手机信号滋扰器的空间之外，手机信号将不会被滋扰、隔央视屏蔽外文减写离，便可恢复正常施用。

When my car broke down, I flagged a police car.

当我的汽车抛锚的时间，我打了个信号招来一辆警车。

To give signal for communication 例如: When my car broke down, I flagged a police car.

当我的汽车抛锚的时候，我打了个信号招来一辆警车。

One feature of this synchronizer was to be able to type the timescale of synchronous signals and choose the time of typing when all the insruments were in...

它的主要特点之一就是在多台测试仪器都处在正常的工作状态中打出同步信号的时标。并且可以任意选择打标的时间。

To convey a message or signal by waving an upraised arm , a flag , or a light .

打旗语发信号，用灯光发信号通过摇摆举起的手臂，旗子或灯来传达信息或记号

Early settlers blew blasts to signal that a sinking ship had been spotted offshore, and native-born islanders are commonly called Conchs.

早期居民吹响它是打信号表明近海发现一沉船，土生土长的岛民被称为海螺壳。

They signaled which way one is going to turn.

他们打信号示意走哪一条路。

When content of Nicotine increased, protein decreased in leaf and root of toped tobacco. This probably because the content of IAA decreased rapidly and acted as the first signal to transfer to root in toped tobacco, and this made the second signal 桝BA and ZR increased, activated biosynthsis of Nicotine.

打顶以后烟碱含量增加的同时，叶和根中的蛋白氮含量均降低，还原糖含量增加，这可能是由于打顶以后，IAA的迅速降低作为第一信号，沿木质部向下运输到根，引起根部的第二信使一ABA、ZR等含量的增加及GA；含量的减少，激活烟碱合成的三种酶，使总氮中用于合成蛋白质的氮减少，自由氨基酸增加，促进烟碱的合成。

This invention discloses an IC phone communication method based on the FSK mode including: loading and transmitting ciphered sequences, ciphered card information, called number information and other interaction information between an IC terminal and a process platform in the mode of FSK information, in which, the platform authenticates the authority and charges, if the deduction at the IC terminal is correct, then it sends signals of anti-stealing making phone calls periodically to the platform, which differentiates the correctness of the signals, if they are wrong, it releases the call, when the communication is finished and the calling rings off first, the platform receives the identification signals of the ring-off of the calling to cut off the call of the called side and release the voice channel between the platform and the called side, then processes balance information and releases the call finally.

本发明公开了一种基于频移键控方式的IC卡电话通信方法，其主要方案是IC卡终端与处理平台之间通过FSK信息方式承载和传输加密序列、加密卡信息、被叫号码信息及其它交互的信息，由处理平台进行鉴权和计费；如果IC卡终端扣费正确则周期性向处理平台发送防盗打信号，处理平台鉴别防盗打信号的正确性，如果错误则释放呼叫；当通信结束后主叫先挂机时，处理平台收到主叫挂机标识信号后首先切断被叫侧的呼叫，释放处理平台与被叫侧之间的话路，然后再进行余额信息的处理和最后释放呼叫。使用本发明提出的方法，使得IC卡终端与处理平台之间的信息交互流程更加简单、清晰，提高了信息交互效率，并能及时释放话路，节约中继资源。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
