Equipment for Data Acquisition and Signal Processing Systemsto Improve Undergraduate Instrumentation Laboratories

将提供三个数据采集和信号处理系统，以实现本科生仪器实验室的新改进。新的理念解决了向机械工程本科学生传授数字数据采集和信号处理技术的需要，如：动态系统响应、数据采样、泄漏、混叠、变换等概念。在新设计的仪器仪表课程中，频谱分析仪的使用与以前使用示波器的方式非常相似。这种本科生仪器仪表的新方法使学生能够学习目前在工业中使用的技术。这些原则不仅将在课堂环境中教授，还将通过两门本科生仪器课程中新设计的实验室实验来教授。该设备将为实验室提供三个工作站，包括个人计算机控制器、数据采集和信号处理外围设备以及适当的信号调节和激励硬件。

Three data acquisition and signal processing systems will be provided to implement a novel improvement in undergraduate instrumentation laboratories. The new idea addresses the need to teach digital data acquisition and signal processing techniques such as: concepts of dynamic system response, data sampling, leakage, aliasing, transformation, and others to mechanical-engineering undergraduate students. In the newly designed instrumentation curricula, spectrum analyzers are being used much like oscilloscopes were used previously. This new approach to undergraduate instrumentation permits students to learn techniques currently used in industry. These principles will be taught not only in the class room environment but also through newly designed laboratory experiments in two undergraduate instrumentation courses. The equipment will provide the laboratories with three work stations consisting of personal computer controllers, data acquisition and signal processing peripherals, and appropriate signal conditioning and excitation hardware.
