One of the InstitutionalWeaknesses reported by ABET was Criterion 3: Assessment and Evaluation stating thateach program had ambitious plans, but neither program had collected data from everyassessment measure. Also, there were no documented examples to show that thecontinuous loop had been closed by way of program improvement.The response to this assessment was that the MET program, realizing the plan was tooambitious for the available resources, decided to benchmark other institutions and thenrevisit the program goals and objectives re-linking them to the a-k criteria to becompleted by April 28, 2006.

At this point, project teams were assigned by the courseinstructors (3 teams of 4 students and 1 team of 3 students) and all project activities werecompleted as a team effort. Student interaction was low and typically had to be prompted in theearly stages of this phase. Later interviews yielded comments indicating that students assumedthat if

From this figure, it is obviousto find that the period of the original signal is much bigger than the modulated signal. Inanother words, the frequency of the modulated signal is much bigger than the originalmessage. The students immediately understood the idea that modulation changes themessage’s frequency and the envelope of the carrier signal looks like the originalmessage. The plot highlights their findings.

Unfortunately, most moderninformation is collected, manipulated, collated, and stored in the digital domain associated withcomputers where data must be a discrete value having limited values for specific times only(Figure 1).The general scheme for converting from the analog domain to the discrete (digital) domain isshown in Figure 2.
