Data Acquisition and Signal Processing Systems to Improve Undergraduate Instrumentation Laboratories

本项目涉及三个数据采集采集和 信号处理系统，以帮助实现一个创新的 在教学方法仪器本科生。 新的方法解决了需要教数字数据采集 和信号处理技术，如：动态系统的概念 响应、数据采样、泄漏、混叠、变换等 机械工程本科生。 在新 设计的仪器课程，频谱分析仪正在使用 很像以前使用的内窥镜。 其意义 一种新的方法来本科仪器是由于这样一个事实， 工业界大量使用这些技术， 学校（至少在机械工程课程）。 这些原则将不仅在教室环境中教授 还通过新设计的实验室实验， 本科仪器仪表课程。 该设备将提供 实验室有三个工作站组成的个人电脑 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.
