are measuring digital signals. This is a violation of Nyquist’s first rule.Most scope vendors don’t specify their scope’s bandwidth at the Nyquist frequency (fN) – butsome do. However, it is very common for vendors of waveform recorders/digitizers to specifythe bandwidth of their instruments at the Nyquist frequency. Let’s now see what can happenwhen a scope’s bandwidth is the same as the Nyquist frequency (fN).Figure 4 shows an example of a 500-MHzbandwidth scope sampling at just 1 GSa/s whileoperating in a three- or four-channel mode.Although the fundamental frequency (clock rate)of the input signal is well within Nyquist’s criteria,the signal’s edges contain significant frequency Aliasingcomponents well

In the first step, thetarget directory structure is built followed by appropriate target files, make files, andhook files. In the next step, the appropriate Target Language Compiler (TLC) files andS-functions of each block are created.

a strong programming capability. The benefits of such a laboratory course are twofold.Firstly, students learn simulation, which is widely used by engineers in the industry to verify andvalidate system designs. Secondly, these laboratory projects have been designed following theGagne‟s nine events of instruction15 which leads to an enhanced learning environment. Also,when compared to hardware based labs, such as with EMONA TIMS16, Mobile Studio17 andEttus USRP18, Simulink has the advantage of lower cost and ease of maintenance.Simulink Laboratory Projects for Communication Systems CourseSix Simulink laboratory projects are constructed to teach Simulink skills in parallel with thetheory.

In keeping with the objective of low cost, a freeversion is available; this version is program memory-limited, but the limit is well above thatneeded for any of the eight projects.

After the computer setup,hardware and software installation, and other issues were solved, we only had less than twomonths left to do the lab projects and design project. With their senior design, other courses, andpart-time jobs, the students didn’t have time to work on the projects outside the dedicated labsessions.Another comment by the students is that some training on GUI design and S-function inMATLAB will be helpful. They did some work on GUI design with the GUIDE component ofMATLAB. However, they didn’t complete the integration of the GUIs with their systemsbecause they didn’t have time to figure out how to display multiple dynamic trajectories (forteam A) or static shapes together with

technical specificationsWhen designing either a transformer or an inductor, a wire is required for the winding(s) aroundthe magnetic core. Wire selection is typically based on the window area of the core as well astolerable amount of copper losses in watts. The web-based magnetic design contains a sub-routine that automatically looks for the wire size (gauge) that most closely fits the calculatedcore material and type. However, since the program is meant to aid in basic calculations ofsimple inductor and transformer designs, the wire selection does not take into account complexconfiguration of winding such as bifiliar or more, interleaving, etc. Figure 5 illustrates the stepwhere wire size is determined including three data related to the selected
