电子信息科学与技术专业本科毕业设计（论文）选题指南 一、电子信息科学与技术专业的学科领域 电子信息科学与技术专业属于电子信息科学类专业。电子信息科学类专业还包括：微电子学（071202）；光信息科学与技术（071203）。 二、电子信息科学与技术专业的主要研究方向和培养目标 1、电子信息科学与技术专业的主要研究方向 (1) 电路与系统 (2) 计算机应用 2、电子信息科学与技术专业的培养目标 本专业培养具备电子信息科学与技术、计算机科学与技术的基本理论和基本知识，受到严格的科学实验训练和科学研究初步训练，能在电子信息科学与技术、计算机科学与技术及相关领域和行政部门从事科学研究、教学、科技开发、产品设计、生产技术或管理工作的电子信息科学与技术高级专门人才。 本专业学生主要学习电子信息科学与技术的基本理论和技术，受到科学实验与科学思维的训练，具有本学科及跨学科的应用研究与技术开发的基本能力。 毕业生应具备以下几方面的知识、能力和素质: (1) 掌握数学，物理等方面的基本理论和基本知识，； (2) 掌握电子信息科学与技术，计算机科学与技术等方面的基本理论，基本 知识和基本技能与方法； (3) 了解相近专业的一般原理和知识； (4) 熟悉国家电子信息产业政策及国内外有关知识产权的法律法规； (5) 了解电子信息科学与技术的理论前沿，应用前景和最新发展动态，以及 电子信息产业发展状况； (6) 掌握现代电路设计自动化技术。 (7) 掌握资料查询，文献检索及运用现代信息技术获取相关信息的基本方法；具有一定的技术设计，归纳、整理、分析实验结果，撰写论文，参与学术交流的能力； (8) 具备善于运用已有知识来学习挖掘新知识，能够将所学知识运用到实践活动中去和运用科学知识分析解决实际问题的能力； (9) 具有独立观察，分析问题，敢于标新立异，勇于置疑，具备开展科学创新活动的基本能力； (10) 善于自我设计、自我推销，协调和处理人际关系，能够及时掌握人才市场需求的信息，具有自主择业的能力。 三、毕业设计（论文）选题原则 本专业毕业论文（设计）题目的选择要遵循以下原则： 1、要结合所学专业 毕业论文主要用来衡量学生对所学知识的掌握程度，所以论文题目不能脱离所学的专业知识。有些学生工作与所学专业没有关系，而本人对所从事的工作有一定的探索或研究，毕业论文就写了这方面的内容。这只能算是工作总结，但不能算是一篇毕业论文。 工科学生学习的专业往往和他们从事的工作有教紧密的关系，他们有教丰富的实验经验和感性认识，经过几年的系统学习，可以学到相应的理论知识，使他们对自己的工作有一种新的认识，他们可以利用所学知识对原来的工作方式、工作程序、工作工具进行改进，以提高工作效率。 2、内容要新 工科论文除了具有理论性之外，更重要的是它的实践性和实际操作性。工科各学科发展非常之快，往往教科书刚进入课堂，内容就已经落后了。待学生毕业时，所学知识可能几近淘汰，所以学生选题要注意所用知识不能陈旧，要能跟上学科的发展。 3、题目要大小适当，难易适度 论文题目不宜过大，否则必然涉及的范围大广。学生处涉科研，普遍存在着知识面窄、理论功底不足的问题，再加上学生主要以业余学习为主，题目太大，势必讲得不深不透，乃至丢三落四，难以驾驭。因此，选题必须具体适中。 题目选择要难易适度。过难，自己不能胜任，最后可能半途而废，无法完成论文；太容易，则论文层次太低，不能很好地反映几年来的学习成绩和科研水平，同时自己也得不到锻炼。 选题最好能合乎个性兴趣爱好，如果自己对论题兴趣很高，就会有自发的热情和积极性，文章就容易写出新意来。 四、毕业设计（论文）选题 选题是决定毕业设计（论文）训练成败与质量好坏的关健之一。 1、电子信息科学与技术专业本科从选题的内容上可以分为理论型毕业设计（论文）和应用型毕业设计（论文）两大类。 2、从本科毕业设计（论文）课题的来源，也可以分为科研开发型和自确定型毕业设计（论文）两大类。 3、从电子信息科学与技术专业本科毕业设计（论文）所涉及的研究领域来看，又可以将其划分为如下一些领域: (1) 集成电路的测试与故障诊断 (2) 集成电路的设计与分析 (3) ARM的设计与应用 (4) 信号与信息处理 (5) 单片机应用系统开发 (6) 仪器、仪表的设计开发与改进 (7) 视频、音频信号处理技术 (8) 可编程器件、EDA技术 (9) 新型电源的开发与应用 (10) 各种电子电路的设计 (11) 微机接口电路的设计 (12) 电子电路的软件仿真技术 (13) 太赫兹电子技术 (14) 测试控制系统的设计与仿真 (15) 数据采集系统设计 (16) 虚拟仪器满意请采纳

毕业设计无所谓了孩纸，电力电子最多还是应用于电机控制啊，所以毕业设计做电机本体也是很好的，再说考研要考电力电子吗？到了研究生再学业赶趟。电力电子两个方向比较火，一个是电机控制，一个是电源。至于电力系统啊，最关键的是功率补偿，其实说白了也是电力电子的知识，神马FPGA啊，单片机啊，都是应用于电机控制的了。
