Data Acquisition and Signal Processing Systems to Improve Undergraduate Instrumentation Laboratories

该项目涉及购买三个数据采集和信号处理系统，以帮助在本科生仪器教学中实施一种创新的方法。新的方法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。这种本科生仪器的新方法之所以重要，是因为工业大量使用这些技术，而学校却没有教授它们(至少在机械工程课程中是这样)。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条件和激励硬件。

This project involves the acquisition of three data acquisition and signal processing systems to assist in implementing an innovative approach in teaching instrumentation to undergraduate students. The new approach 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. The significance of this new approach to undergraduate instrumentation is due to the fact that industry heavily uses these techniques while they are not taught in the schools (at least in mechanical-engineering curricula). 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 condition and excitation hardware.
