说明：  MathCAD是美国Mathsoft公司推出的一个交互式的数学软件。该软件定位于向广大教师、学生、工程人员提供一个兼备文字处理、数学和图形能力的集成工作环境，使他们能方便地准备教案、完成作业和准备科学分析报告。在输入一个数学公式、方程组、矩阵之后，计算机能直接给出结果，而无须去考虑中间计算过程。在加入软件包自带的Maple插件后能直接支持符号运算。你可以在计算机上输入数学公式、符号和等式等，很容易地算出代数、积分、三角以及很多科技领域中的复杂表达式的值，并可显示数学表格和图形,通过对图形结果的分析，使我们对问题的理解更加形象。 在实际应用中，MathCAD好比是一个功能强大的计算器，它没有很复杂的规则；同时它也可以和Word等字处理软件很好地配合使用，所以也可以把它当作一个出色的全屏幕数学公式编辑器来使用。 Mathcad的用户主要针对具备应用数学知识但并不要求具有较多的计算机知识的用户，如工程研究人员、学生等。 (MathCAD is a Mathsoft Launches interactive mathematical software. The software is targeted to the vast numbers of teachers, students, engineers to provide a mix of word-processing, mathematics and graphics capabilities of the integrated working environment, so that they can make it easier to prepare lesson plans, homework and prepare for scientific analysis. In the importation of a mathematical formula, equations, matrices, the computer can directly give the result without the need to consider the middle of the calculation process. Before joining the Maple software package comes with plug-ins can directly support the operation symbol. You can enter a computer mathematical formula, such as symbols and equations, it is easy to calculate the algebra, Integral, Triangle, and many of the complex field of science and technology in the value of expression, and mathematical tables and graphics show through an analysis of the results of graphics so that our understanding of the issues more imag)

用matlab画出α=0,0.5,1的余弦滚降系统的频谱，并画出各自对应的时域波形。以α=1的余弦滚降系统为例，进行二进制双极性数字基带信号传输，试画出接收端的基带信号波形及眼图。(Matlab draw α = 0,0.5, 1 cosine roll-offs system of spectrum, and draw their corresponding time domain waveform. To α = 1 cosine roll-offs system as an example, the binary dual polarity digital baseband signal transmission, try drawing the receiving end baseband signal waveform and eye chart.)
