Many communication topics are difficult for undergraduate students to internalize, but demonstrations and laboratory experiences have been shown to help a great deal. This paper describes how we teach the concept of frequency shift keying by using a highly successful combination of theory, demonstrations, lab exercises, and real-time DSP experiences that incorporate MATLAB and the Texas Instruments...
A set of seven audio digital signal processing (DSP) lab assignments have been developed for intermediate and advanced students in electrical engineering. The laboratory modules are designed to bridge the gap between a solid understanding of the mathematical principles of DSP and the practical issues that arise when implementing algorithms for real time audio processing. The audio DSP lab assignments...
Audio recordings of gunshots can provide information about the gun location with respect to the microphone(s), the speed and trajectory of the projectile, and in some cases the type of firearm and ammunition. Recordings obtained under carefully controlled conditions can be well-modeled by geometrical acoustics. Special acoustic processing systems for real time gunshot detection and localization are...
Electrochemical impedance spectroscopy (EIS) methods are commonly used to estimate the performance of corrosion resistant coatings. A multi-frequency EIS improves performance over traditional EIS systems through shortened trial times. With the addition of real-time performance monitors, a multi-frequency EIS system provides users with a better understanding of estimate quality and automatically adjusts...
This paper describes several types of matching exercises for introductory digital signal processing. The paper presents example exercises in four areas of DSP: the discrete Fourier transform, weighted least square FIR filter design, minimum-phase FIR filters, and the short-time Fourier transform. These exercises tests for conceptual understanding of important concepts rather than computational ability
This paper introduces the concept of scholar teams (STs), discusses strategies to successfully implement STs, overviews the results of the first two years of comprehensive ST trials conducted in the Electrical and Computer Engineering (ECE) department at North Dakota State University (NDSU), and details a specific ST, the digital signal processing (DSP) ST, to illustrate the benefits of STs, particularly...
Many of today's most popular consumer electronics products rely, to some extent, on digital signal processing (DSP) algorithms and chips. The development of this course had the primary goal of educating students outside electrical engineering about some basic signal processing concepts and applications. For this reason, the focus of the course is on the breadth of applications and includes some hands-on...
In a traditional course on phase-locked loops (PLLs) with applications, analog PLLs are the major focus. Indeed, there are many PLL fundamental topics that need to be understood before moving on to applications. It is within the context of this course that the need to expose the students to pure digital signal processing (DSP) based synchronization arises. To introduce synchronization using a pure...
Arizona State University's electrical engineering department is redesigning its Freshman introduction to engineering design course with the objective of increasing students' retention and the students' interest in engineering careers. National instruments (NI) products, including the LabVIEWtrade embedded DSP module, which supports embedded real-time solutions, the SPEEDY-33 DSP board, and the NI...
We study the use of project-style assignments to facilitate student learning in an introductory graduate-level DSP course. Specifically, we aim to help students understand fundamental DSP concepts, draw connections between theory and practice, and develop motivation to learn the course material. Weekly homework assignments, used in the Fall 2005 semester, were replaced by four larger-scale projects...
