Personal Statement

My interest in electric engineering dates back to the time when I was very little. My father was engaged in a research on electronics and he often took me to his laboratory. As time went by, those complex and delicate electronic instruments made profound impression on me, directly leading to my enthusiasm for the world of electronics. Thus, I chose to major in Electronics and Information Engineering in Sichuan University. And as my study progressed, I gradually honed my skills and developed my huge interest in signal extraction and circuit design. It was then I became aware of my drawbacks and realized pursuing the advanced study in MS program in the United States is my goal.

I have developed a wide range of interests in every branch of electric engineering in college. I have mastered relevant applications of electronic knowledge in economy through participating in the National Contest for the Application of Information Technology. I have also acquired a more comprehensive understanding of network engineering through the internship in Sichuan Hwadee Information Technology Co., Ltd. However, I am fully conscious that my future research orientation is bound to be in the field of telecommunication and signal. I was immensely captivated by the crafty signal changes and the ingenious analysis and design of the circuit the first time I got contact with signal and its system, and my curiosity for this field has never ceased growing since. I have obtained outstanding grades by putting in tremendous efforts and become increasingly interested in signal analysis and processing as my study progresses.

        In my sophomore year, in order to learn more about signal and forge my ability in practical operation, I applied for a two month summer internship in No. 22 Research Institute of China Electronic Technology Group Corporation where I undertook the study of the detection and extraction of weak signal under Mr. Sun’s guidance and acquired a specific understanding of the hardware (front-end conditioning circuit and date acquisition circuit) structure and the whole working principles and procedures of the weak signal detection and extraction system, but the understanding was quite conceptual due to my inadequate hands-on experience. Therefore, I was facing a great challenge in learning how to put theories into practice.

With the challenge in mind, I went on studying in the third year when I put more emphasis on the integration of basic knowledge and engineering application by consulting relevant materials in my spare time, strengthening my ability in operation and engineering practice in the laboratory, and taking courses in digital signal processing and random signal analysis. In the third summer vacation, I assisted Mr. Sun to work in the engineering application of weak signal detection and extraction. During this internship, Mr. Sun designated a specific task to me to build a data acquisition circuit which I accomplished under his guidance by using the SSM2141 differential amplifier (which converted the differential signal into a single output signal), the LT1355 high-speed operational amplifier (which amplified the single end signal, the amplitude of which was made between A/D chip analog input voltage range), the ADC 12062 analog-digital conversion chip (which made the analog to digital conversion possible), the DSP (used in digital filtering, digital notch filtering, signal processing, etc.) and several peripheral circuits. It was on the data acquisition circuit that I analyzed the extracted weak signal by means of FFT. During the process I discovered that it was hard to extract signal when the SNR was weak, which turned out to be a prevalent problem existing in the extraction of weak signal after I consulted relevant materials. In light of this, I am resolute to pursue further study in signal analysis and processing at graduate level in the U.S. to enhance my capability .month summer internship in No. 22 Research Institute of China Electronic Technology Group Corporation where I undertook the study of the detection and extraction of weak signal under Mr. Sun’s guidance and acquired a specific understanding of the hardware (front-end conditioning circuit and date acquisition circuit) structure and the whole working principles and procedures of the weak signal detection and extraction system, but the understanding was quite conceptual due to my inadequate hands-on experience.

最后一段根据各学校的特色来写的还没有加上，麻烦各位大神帮忙看下吧，不胜感激啊~~

还有就是research这块会不会写的有点啰嗦了？（感觉全文写的会不会有点单调？）

补充内容 (2013-11-12 10:01):
额。。。不知道为啥发上来变成乱的了。。。我重新发一遍

楼主专业的知识我不懂啊。。但是倒数一段研究经历真的太长了。。有点看不下去的感觉。。看看能不能精简一点。。我觉得重要的不是你做了些什么。而是怎么做，有什么挑战和收获，还有它如何促使你要去深造这些。。。另外，开头还可以想想能否更吸引人些

嗯 最后一段不知道为什么发上来就变乱了 原来没有这么长的。。。。
不过还是十分感谢 受教了~~

楼主你最后一段和中间的一个部分是不是重复了，你是不是没有贴对内容啊？

嗯嗯是的 不知道为什么贴上来变乱了 我后来又重新发了一遍。。

还是乱的……不过我整理了一下看了看，我也在改ps，所以不敢说很权威，就是说点看法，先说优点，就是字数控制的很好，其次就是有一条明确的主线，写出了自己兴趣的发展过程。我觉得问题在于，第一最后一段太长了，感觉结构不太平衡，还有就是学术内容偏多，可以在酌情再体现一些自己的能力，技术细节可以简要一些

嗯 谢谢你的意见 很中肯~~
展现自己一些能力的部分是指社团活动或者志愿者活动么？可是如果这些经历和申请的方向不match怎么办？（现在感觉除了科研方面真不知道PS里还应该写点什么了。。。）
还有就是我申请要SOP 看论坛上说SOP偏学术，PS偏生活 那对于SOP来说除了科研意外还应该写些什么经历呢？

不是不是，不是说社团活动，而是说你在描述你的例子的时候可以体现一些，比如你说你做研究，怎么研究的，方法是什么，而不是很多很多的学术内容，其实再多的学术内容也还是一件事情嘛

哦哦 这样啊 嗯 那我再根据你的意见改一下 谢谢了~
