Intermediate multiplicationresults are stored as 32 bit integers in Q24 through Q30 format, respectively, with all final resultsstored as 16 bit integers. The fixed-point filter implementation is constrained by the DSK’smemory and processing limitations to a 254 order IIR Direct Form Type II transpose and a 200order IIR cascaded second order section.A companion program for teaching DSP using MATLAB and the `C31 DSK, which allowsstudents to perform interactive adjustment and “what if?” analysis of a pole-zero plot, is describedin an accompanying paper18 by Welch, Wright, and Morrow.3

Of the more than 1200students on campus, roughly one-half are enrolled in the School of Engineering and Science(SOES).Begun in 1909, the Chemical Engineering (ChE) Department at TSU has remained a smallundergraduate program with a focus on career-oriented higher education.

semester of the sophomore year. Because of the relative size of the Mechanical andIndustrial Engineering programs, the vast majority of the students are Mechanical Engineeringmajors. The first circuit theory course is a pre-requisite to CPE240. Historically, the course was initiated in the early 80’s in response to the increased use ofPC’s to take measurements on non-electrical systems. There was extensive laboratorycurriculum development at that time, mostly in the area of digital circuits and A/D and D/Aconversion. Typical transducers were covered in the lecture portion of the course, but the labswere primarily devoted to digital and analog circuit analysis and testing. During much of the90’s the course was taught by adjuncts and there

It is easy to show the students themagnitude of error resulting from poor coordinate measurement by simply moving the supportpoint of a string from one support point to the next adjacent one. Accuracy of the experiment wasgenerally good, and this proved to be an effective learning experience. When tested on concurrentforces later in the course, the students did quite well.Analysis of Pinned Connections. Approximately 20 pinned connections were constructed fromwood (Figure 2). Groups of four students were required to examine a connector and measure thedimensions of each member and the pin(s). Based on these dimensions and an assumed axial
