Description:
游戏控制 W,A,S,D, P
unit, pic, audio目录不可缺少
只用研究StillObject.cs Tank.cs GameForm.cs即可编程，非常简单
每一个类继承 LifeObject类 首先研究StillObject.cs
然后研究Tank.cs
其中重要的几点是
UnitID 表示物体对应的图片 放在pic目录下
Behave 每回合系统调用此函数执行物体自身的行为
Show 显示函数
RunInto 当物体撞上其他物体时，系统会调用此函数进行处理
Disppear 当物体消失，可调用此函数从游戏世界中退出
然后研究 GameForm 的 Initial 函数 加入你自己的物体即可
所有物体若要从游戏世界中退出 只需调用其Disappear()函数
举例在 GameForm 的ProcessCmdKey(ref Message msg, Keys keyData)中
flower.Disppear()
-Game Controls W, A, S, D, P unit, pic, audio catalog indispensable research StillObject.cs Tank.cs GameForm.cs only to programming, very simple class that inherits LifeObject each class and then study the first study StillObject.cs Tank.cs One of the important points are UnitID represent objects corresponding picture on pic directory Behave per round system calls this function to perform the behavior of the object itself functions RunInto Show Displays when an object hit other objects, the system will call this function processing Disppear when the object disappears, you can call this function to exit from the game world and then the Initial research GameForm function to add your own objects to all objects To exit from the game world simply call it Disappear () function is an example of ProcessCmdKey in GameForm (ref Message msg, Keys keyData) in flower.Disppear ()

Description: low-power 16-bit CMOS D/A converter for portable
digital audio is described. The converter is based on current division. To
guarantee monotonicity and a good small-signal reproduction, a dynamic
segmentation technique is used. A geometric averaging technique is used
to minimize the harmonic distortion of the converter at high signal levels.
The dynamic range is 95 dB.

Description: The Arduino MP3 Shield has an onboard 3W Class-D stereo audio amplifier which could drive 4ohm load such as loudspeaker.
The Arduino MP3 Shield has seven buttons and a UART interface, that is to say user has two ways to control the module flexibly. The UART interface is connected to the Arduino hardware UART by default. Since most Arduino boards have only one UART interface, this module’s UART interface can be redefined to Arduino D7 (TX) and D8 (RX) through the jumpers on board. With SoftSerial lib, Arduino could also send data to this module.
We tested with 8G SDHC card and 16G U-disk. It works in perfect compatibility. We haven’t tested larger SD and U-disk yet.

Description: 在一个移动通信系统中，发射信号是一个未调制的音频x(t)=cos(2πft)，其中f=f0+fi。设标称载波为f0=1GHz，并设fi =512Hz。假定移动用户在一个繁忙的高速公路上距离基站l公里处的地方，从开始从每小时60公里的速度开始，其速度（在0.01秒的时间间隔内测量）以1/2的概率随机的增加或减少1/10公里每小时。试仿真移动用户在这2s的时间间隔内所接收到的信号(及其频谱)。接收信号可以表示为：
y(t)=a(t)Cos[2π(fo+f1)(t-△t)]
式中 △(t)=d(t)/c
且 a(t)=k/d2(t)
在上面的表达式中d(t)是在t时刻基站与移动用户的距离，c是光速，△(t)是传播延迟，而a(t)是信号在t时刻的衰减，并假设在这2s内a(t)是一个常数。利用复低通等效模型来进行仿真。-In a mobile communication system, the transmitted signal is an unmodulated audio x (t) = cos (2πft), where f = f0+ fi. Let nominal carrier of f0 = 1GHz, and set fi = 512Hz. Assume that mobile users on a busy motorway station l kilometers place, starting the beginning of 60 kilometers per hour, the speed (measured in 0.01 second interval) to increase the probability of a random 1/2 or reducing 1/10 km/h. Simulation test signal which the mobile subscriber in the 2s time intervals of the received (and its spectrum). The received signal can be expressed as:
y (t) = a (t) Cos [2π (fo+ f1) (t- △ t)]
Where △ (t) = d (t)/c
And a (t) = k/d2 (t)
In the above expression, d (t) at time t is a base station and a mobile user s distance, c is the speed of light, △ (t) is the propagation delay, and a (t) is the attenuation of the signal at time t, and assuming that 2s within a (t) is a constant. Using complex low-pass equivalent model for emulation.
