Effective Utilization of the Analog Discovery Board Across Upper-Division Electrical Engineering Courses

Abstract

To date, the electrical engineering education literature has presented the Digilent Analog Discovery board with a focus on usage in lower-level circuits courses and as merely a low-cost replacement for bench-top signal generators and oscilloscopes. This work broadens the domain of the Analog Discovery board beyond introductory courses, and demonstrates its use as a powerful educational tool for junior and senior level coursework. By utilizing its full suite of measurement features, sophisticated laboratory experiments are possible in courses such as electromagnetics, digital signal processing, signals and systems, communication systems, and control systems. In addition, its inherent mobility allows insightful in-class demonstrations and "lab-like" activities to be incorporated into theory-focused courses that otherwise do not have a lab, an impossible feat with traditional anchored, expensive laboratory equipment. In this paper, the unique measurement features of the Analog Discovery that are especially appropriate for upper-level courses are detailed, such as the network analyzer and spectrum analyzer modes. Selected demonstrative lab experiments from upper-division courses at the Milwaukee School of Engineering (MSOE) are then presented. Emphasis is placed on how these experiments are both enabled by the Analog Discovery board as well as constrained by the performance limits of the board, such as limited frequency response and power supply rails. As a result, careful experiment design is shown to be critical to the classroom success of these projects.

BYOE: Individual Lab Kit Options for Analog and Digital Circuits Suitable for In-class or At-home Experiments

“…The individual lab or project kits also allow interdisciplinary collaborations [5] [7]. Despite the pioneering exploration of using individual lab kits in undergraduate engineering curriculum [9], [12], [16]- [20], their usage had been sporadic before the pandemic, except perhaps in the mechatronics programs. However, the lab kits used in the mechatronics programs tend to be modulized and specific for a particular course [15], rather than being fundamental but versatile and expandable for the students to use in multiple courses throughout their undergraduate study.…”

Board 208: Achieving Active Learning through Collaborative Online Lab Experiences

“…Moreover, the EE virtual lab experiences have much more possibilities without being limited to lab courses. The project team and faculty in EE successfully integrated laboratory experiences into purely theoretical courses via Hardware-in-Homework (HiH) concept [13,14]. The Analog Discovery kit is a good example of HiH, which can play an important role for students who learn EE materials in an online setting.…”

“…The Analog Discovery kit is a good example of HiH, which can play an important role for students who learn EE materials in an online setting. The unique measurement features of the Analog Discovery kit can be appropriately applied to lower to upperlevel courses [14]. Due to its readily available and portable nature, it will be beneficial for students who learn well with hands-on activities.…”
