Engineering - Electrical (55)Arizona State University is fully developing and evaluating a web-based undergraduate laboratory tool in the areas of undergraduate digital signal processing(DSP), communications, image processing and controls. We have already developed and successfully tested a prototype laboratory tool (J-DSP) for use in the undergraduate DSP class. This web-based prototype supports capabilities for online signal processing simulations and provides laboratory experiences to distance learning and on-campus undergraduate students. The tool is based on a collection of novel Java applets that support a user-friendly object oriented environment. This exemplary Java software supports a simulation environment that enables students to establish and execute experiments from any computer platform that is equipped with a web browser.This work provides significant extensions of the laboratory prototype to the other areas (communications, image processing and controls), an assessment and dissemination strategy that includes test sites, and a plan to sustain development, dissemination, and evaluation after the CCLI project. The prototype lab and the proposed extensions represent perhaps the first comprehensive effort to provide on-line lab experiences in distance learning environments. We anticipate that this novel concept can be extended to different types of subjects at different levels of education, e.g., on-line experiments at levels and topics ranging from high-school physics to community college science labs and college-level engineering subjects. The prototype J-DSP along with its proposed extensions to "hot" systems topics such as communications, image processing, and advanced controls will enable new web-course developers to seamlessly integrate online experiments to their web-course content.

工程-电气（55）亚利桑那州立大学正在全面开发和评估基于网络的本科生实验室工具，在本科生数字信号处理（DSP），通信，图像处理和控制领域。我们已经开发并成功测试了一个原型实验室工具（J-DSP），用于本科DSP类。这个基于网络的原型支持在线信号处理模拟功能，并为远程学习和在校本科生提供实验室体验。该工具是基于一系列新颖的Java小程序，支持用户友好的面向对象的环境。该示范性Java软件支持模拟环境，该模拟环境使学生能够从配备有web浏览器的任何计算机平台建立和执行实验。（通信、图像处理和控制），包括试验场在内的评估和传播战略，以及持续发展、传播、CCLI项目后的评估。原型实验室和拟议的扩展代表也许是第一个全面的努力，提供在线实验室的经验，在远程学习环境。我们预计，这一新颖的概念可以扩展到不同教育水平的不同类型的科目，例如，从高中物理到社区大学科学实验室和大学水平的工程学科，都有不同层次和主题的在线实验。原型J-DSP沿着其对“热门”系统主题（如通信、图像处理和高级控制）的拟议扩展，将使新的网络课程开发人员能够将在线实验无缝集成到其网络课程内容中。
