— Digital Signal Processing Demonstration Software

As a project of a DSP course in BIT, Mr.Alpaca is a digital signal processing demonstration software, which gives intuitive feelings of complex DSP methods to learners. The software is implemented by a combination of MATLAB and VB.NET, which gets advantages of each one, i.e. the user interface design of VB.NET and the scientific calculation of MATLAB.

Mr.Alpaca是北理工的一个数字信号处理课程设计作业，这是一个用来进行数字信号处理演示的软件，可以给DSP的初学者提供对于纷繁复杂信号处理方法的直观感受。该软件采用MATLAB和VB.NET混合开发的方式，将二者的优点结合了起来，即：采用了VB.NET的界面设计、MATLAB进行科学计算。

It is known that visual demonstration of algorithms enhances students’ understanding. Algorithms are abstract and hard, and coding is tiring. Digital  Signal Processing needs a software to demonstrate the use of different filters and variety of spectrum estimation.

大家都知道对算法的视觉演示能够增强学生的理解，算法既复杂又抽象，数字信号处理也不例外。这个学科包含了各种滤波器和谱估计问题。

Features 特性

• Flexible Signal Control: The software supports arbitrary superposition among signals (basic sine, square, and noise signals), setting or deleting in batch, and switchability between analog or digital analysis methods;
• 灵活的信号控制：软件支持信号（基本的正弦、方波、噪声信号）的任意叠加、批量设置和删除、数模分析模式的可转化；
• Friendly Notifications: The software uses information bubbles, tool tips, process bar, and status bar to help users get well;
• 友好的信息提示：软件使用信息气泡、悬浮标签、任务栏、状态栏帮助用户熟悉软件功能；
• Reliable Specifications: The software validates the correctness after user’s setting and gives corrective suggestions;
• 可靠的参数配置：软件会校验用户设定的参数，并提出改正建议；
• Engaging View: It provides a new-window view method, which allows users to compare two new result with a previous one.
• 令人心动的显示方式：软件提供新窗口查看的方式，用户可以将新旧结果进行对比。
