1引言科学技术的飞速发展对高校人才培养提出了新的课题,并对重新构建专业的知识结构提出了要求。然而电子信息类专业除了面对电子信息技术的快速发展,还要面对瞬息万变的电子产业市场。在电子信息类专业中,基础课的中心正在慢慢转移。电子器件经历了电子管、晶体管到集成电路的发展,信号处理也正从模拟信号体制逐步过渡到数字信号体制。分立器
1 Introduction The rapid development of science and technology has raised new topics for personnel training in colleges and universities, and put forward requirements for reconstructing the professional knowledge structure. However, in addition to the electronic information industry in the face of the rapid development of electronic information technology, but also to face the ever-changing electronic industry market. In the electronic information specialty, the basic course center is slowly transferred. Electronic devices have gone through the tube, transistor to the development of integrated circuits, signal processing is also gradually transition from the analog signal system to the digital signal system. Discrete device
