As the students advance through the signal processing curriculum,they will transition from high-level algorithm generation to hardware-level design andimplementation. This hierarchical training will provide a thorough, extended, and increasinglyfocused exposure to signal processing.1. IntroductionDigital signal processing (DSP) is central to modern Electrical and Computer Engineering (ECE)undergraduate curricula. The discipline of signal processing combines an extensive mathematicalbackground with practical design skills. To prepare for a successful career in signal processing,whether in industry or academia, students should develop

These same people find theirproblem-solving skills seriously lacking.There seem to be three primary reasons why soft-side skills are missing from the students’ “bagof tricks”: 1) It is difficult to fit them into technical courses; 2) humanities courses generally donot cover the broader spectrum of such skills; and 3) students often do not understand theimportance of learning such skills. Technical courses are usually full of all the informationnecessary to turn out technical experts, and teachers are hard

It appears that the timespent on this endeavor would have been better spent in making direct, though possiblyundirected , improvements to individual courses.The direct changes resulting from response to ABET observations are agreed to be ofvalue.

It wasestablished as a full Department of Engineering Management in the school of Engineering July1, 1968.” (1) Engineering Management is considered “non-traditional” as it bridges the gapbetween traditional engineering and management by highlighting communication and peopleorientation. This sometimes is the reason for it to be thought of as “less” of an engineeringdegree compared to other more “traditional” ones like Mechanical or Electrical Engineering.The same problem often plagues other hybrid fields. A recent study of student perceptions ofIndustrial Engineering (2) demonstrated a similar lack of appreciation and understanding. Yet,Engineering Management at the

The use of LEGO projects, such as thosedone by Branoff [1] and Buchal [2] has been shown to be effective in teaching some of the basicsof parametric modeling and teamwork. Even though a LEGO toy was used in this project, anysimilar object composed of rather simple yet discrete parts would have been appropriate for useas long as the parts and their connectors were standard so the parts would be interchangeable.When using a toy, such as the LEGO backhoe, it

innovations. Student misconceptions are not random, but are generally theresult of a deficiency in their understanding of fundamental principles. The source of thesemisunderstandings, as identified by Clement [1] and others (see, for example references [2–7]),can be traced to deeply-seated preconceptions that make the complete understanding offundamental principles very difficult. In order to create a new conceptual frameworkand to displace the existing one that has been ingrained over many years, new teachingmethodologies have to be established. Concept inventories are an excellent instrument withwhich to validate the effectiveness of these new methodologies. At the 2003 ASEE AnnualConference, we revealed that we were developing a Dynamics Concept

They then designedand analyzed the frame and foundation and selected materials for both the frame and surfaces.Significant testing of various material combinations was performed. The sculpture was completed in September 2004. President DeFleur of BinghamtonUniversity dedicated it on 1 October 2004. The incorporation of a senior capstone design courseinto the proposal to obtain funding for a community project is one of the unique features of thisproject.

other trains. Using this as the starting point,we began design. Almost immediately, physical space became a major concern. Our labs are nothuge, and having train tracks running the lengths of rooms was not an option. In addition, therewere concerns about storage and how to avoid damage to the project. As a result, we scaleddown the project to the point where we took a single four foot by eight foot sheet of plywood andcut it in half, leading to our first design constraint: length of track. This led to the next step whereentire trains were replaced by single railroad cars. Given all this, a candidate track layout usingHO gauge model railroad stock was designed, and is shown in Figure 1 below. Figure 1

CPU in mind. However, we areattempting to finally design and implement a simple architecture without sacrificing theimportant and basic issues in such design. For example we need first to address thefollowing issues: word length, memory size, and registers. These can also be restated ormodified without in another design once the methodology is adhered to. Since we areadopting a previously published design, the first two steps in our methodology would beto define our basic computer: 1. 16-bit data wordlength and 12-bit memory address. The wordlength size can address double precision data more readily than 8-bit designs, yet it adds little overhead in our methodology. The memory size will not be too prohibitive for
