photoshop软件(本例中使用CS5版本,当然各版本界面都大同小异) 界面篇 1 首先我们打开photoshop软件,界面就如下图所示了: 2 左侧的是工具箱调板,我们可以用鼠标单击相应的工具进行图片处理操作,鼠标右击可以进行某一工具选择(再使用熟练后,我们也可以按下相应的键盘键进行选择),如图: 3 右侧的是窗口调板,我们可以点击菜单中的窗口菜单,在下拉列表中选择我们需要的窗口调板,如图: 4 顶部的菜单栏中包含了全部photoshop常用的操作,我们不必去死记硬背,只要平时常用就会烂熟于心了。 5 在菜单栏的下方是属性栏,显示当前我们正在使用的工具的属性,如图: END 常用操作 1 打开一张图片,方法有三种:①使用菜单里面的打开命令;②使用快捷键Ctrl+O;③双击photoshop界面中心;④拖动想要处理的图片到photoshop中打开;⑤右键选择要处理的图片选择使用photoshop打开命令。 2 保存图片的方法:一般按下键盘上的快捷键Ctrl+S,或使用菜单保存命令(如果要另存的话就选择另存为选项;保存的图片可以选择任意格式,.psd是保存当前处理的所有步骤,下次打开还可以继续编辑,JPEG、png、gif格式就是处理好的图片格式) 3 历史记录面板的用法:我们处理图片的时候可能要反复修改获得最佳的效果,那么历史记录工具就可以很方便的返回之前我们的操作状态,如图,点击要恢复的步骤,即可恢复图片: END 使用技巧 如图所示黑色是前景色、白色是背景色,我们可以按下键盘上的X键进行前景色和背景色的互换: 图片移动操作,我们打开两张图片,想要移动其中的一张到另一张中,我们可以按住键盘的Ctrl键,使用鼠标拖动一张图片到另一张图片中,如图: 3 我们可以在处理图片的时候按下Z键使用放大镜放大图片的细节,处理图片的时候就会容易许多,我们可以按ATL键在放大和缩小之间切换! 4 我们可以按住键盘上的空格键,移动图片,对于处理大型的图片还是非常方便的! END 注意事项 photoshop入门相对来说比较简单,但熟练操作至少要3个月左右! 精通photoshop是一条非常漫长的路程,有时候会打退堂鼓,但只要多操作,多制作,慢慢的时间久了也就精了。

Digital radios have undergone an astonishing evolution in the last century. Born as a set of simple and power-hungry electrical and electromechanical devices for low data rate transmission of telegraph data in the Marconi age, they have transformed, thanks to substantial advances in electronic technology, into a set of small, reliable and sophisticated integrated devices supporting broadband multimedia communications. This, however, would not have been possible unless significant progress had been made in recent decades in the field of signal processing algorithms for baseband and passband signals. In fact, the core of any modern digital radio consists of a set of algorithms running over programmable electronic hardware. This book stems from the research and teaching activities of its co-authors in the field of algorithmic techniques for wireless communications. A huge Body of technical literature has accumulated in the last four decades in this area, and an extensive coverage of all its important aspects in a single textbook is impossible. For this reason, we have selected a few important topics and, for ease of reading, organized them into two parts.

Electrostatic discharge (ESD) is one of the most prevalent threats to the reliability of electronic components. It is an event in which a finite amount of charge is trans- ferred from one object (i.e., human Body) to another (i.e., microchip). This process can result in a very high current passing through the microchip within a very short period of time, and, hence, more than 35% of chip damages can be attributed to an ESD-related event. As such, designing on-chip ESD structures to protect integrated circuits against the ESD stresses is a high priority in the semiconductor industry.

December 2007, San Jose, California: It seems a long time ago. I walked into a big networking company to head their small Power over Ethernet (PoE) applications team. Surprisingly, I hardly knew anything about PoE prior to that day, having been a switching-power conversion engineer almost all my life. But it seemed a great opportunity to widen my horizons. As you can see, one notable outcome of that seemingly illogical career choice five years ago is the book you hold in your hands today. I hope this small Body of work goes on to prove worthy of your expectations and also of all the effort that went into it. Because, behind the scenes, there is a rather interesting story to relate—about its backdrop, intertwined with a small slice of modern PoE history, punctuated by a rather res- tive search for our roots and our true heroes, one that takes us back almost two centuries

Despite the development of a now vast Body of knowledge known as modern control theory, and despite some spectacular applications of this theory to practical situations, it is quite clear that much of the theory has yet to find application, and many practical control problems have yet to find a theory which will successfully deal with them. No book of course can remedy the situation at this time. But the aim of this book is to construct one of many bridges that are still required for the student and practicing control engineer between the familiar classical control results and those of modern control theory.
