一、指导思想与理论依据随着现代信息技术的发展,数字技术已经和我们生活越来越近,联系越来越密切,因此有必要对数字技术有所了解。学生对于模拟信号、数字信号学习起来困难较大,不能很好地掌握。因为他们对计算机基础、二进制不熟悉,并且“与”“或”“非”三种基本逻辑运算,是与学生学习的二进制和普通代数完全不同的运算。因此初始接触学生很不习惯二进制的运算。根据学生的原有知识水平,让学生以学案式提前讨论预习,课堂充分利用现代信息技术手段,把模拟
First, the guiding ideology and theoretical basis With the development of modern information technology, digital technology has become closer and closer to our life, closer and closer, so it is necessary to understand digital technology. Students for analog signals, digital signals difficult to learn, can not properly grasp. Because they are not familiar with computer fundamentals and binary systems, and they have three basic logic operations: “and ” “or ” “not”, they are completely different operations from the binary and ordinary algebra that students learn. So initial contact with students is not used to binary arithmetic. According to the students’ original level of knowledge, students should discuss and preview the lesson in advance, and make full use of modern information technology in the classroom. The simulation
