This project establishes a teaching laboratory for undergraduate instruction in digital signal processing (DSP). The laboratory gives students practical, hands-on training in DSP concepts and techniques using modem hardware and software design tools that complement the more theoretical approach of a lecture course in DSP. The laboratory uses PC-type workstations with add-on DSP processing boards and a complement software to provide both non-real-time and real-time DSP environments for algorithm development and testing. The new laboratory course consists of a dozen laboratory exercises, about one per week during the semester, each emphasizing a particular topic in DSP (for example, convolution, sampling, filter design, and Fourier transformation). In the laboratory, students program non-real-time simulations of common DSP procedures using MATLAB and compare the results of these simulations with theoretical predictions. They then implement these same DSP procedures in real time using a hardware/software system that allows them to graphically program a DSP coprocessor card. Students have the opportunity to visualize and hear the results of applying real-time DSP procedures to real-world signals such as speech and music. The proposed laboratory augments and enhances offerings in the School of Engineering and the Department of Computer Science in digital signal processing, control and robotics, computer music, and multimedia.

该项目为数字信号处理（DSP）的本科教学建立了教学实验室。 该实验室使用调制解调器硬件和软件设计工具为学生提供了DSP概念和技术的实践，动手培训，以补充DSP中讲座课程的理论方法。 该实验室使用附加DSP处理板和补充软件的PC-Type工作站来提供非实时和实时的DSP环境，用于算法开发和测试。 新的实验室课程由十几个实验室练习组成，每周大约一个学期，每个实验室练习都强调了DSP中的一个特定主题（例如，卷积，采样，滤镜设计和傅立叶变换）。 在实验室中，学生使用MATLAB对常见DSP程序进行非真实时间模拟，并将这些模拟的结果与理论预测进行比较。 然后，他们使用硬件/软件系统实时实现了这些相同的DSP过程，该系统允许他们以图形方式编程DSP协处理器卡。 学生有机会可视化和听到将实时DSP程序应用于语音和音乐等现实信号的结果。 拟议的实验室增强并增强了工程学院和计算机科学系在数字信号处理，控制和机器人，计算机音乐和多媒体方面的产品。
