Applications sliding toolbars which allow a smooth variation of property values. Properly used by students, these worksheets have the potential to reinforce and enhance understanding of the fundamental interrelationships among various properties; students are free to change various parameters such as pressure, temperature, and quality, and immediately view the effect of these changes on the associated Mollier and T-s diagrams. Students may quickly visualize the effect of these changes, rather than being mired in the minutiae of table lookups, interpolation, transcription, and manual plotting. An additional benefit of the rapid and very accurate plotting of thermodynamic properties is a better

After revisions based on this round of testing, the game segments are testedfor instructional impact. This round of testing involves interviews, “think aloud”strategies, and pre/post surveys to test content knowledge.Motivation for the ProjectThe use of digital games has grown exponentially since the early 1980’s, when personalcomputers first appeared.

Overall theslight increase in average score is consistent with the expected average increase if eachstudent were instead offered another online attempt. The clear conclusion fromexamining the average scores and the standard deviations (s) is that little, if any, testingbias is introduced by offering the test online versus the more traditional paper/opscanmethod.

This modulator is capable of operating at up to 200 millionsamples per second (MS/s), with a resulting carrier or intermediate frequency of up to 80 MHz(i.e., 40% of the system’s sample frequency). An onboard 32-bit direct digital synthesizer (DDS)is used to generate the carrier waveform values. Baseband 14-bit in-phase and quadrature (I/Q)data are presented to the modulator, which can be programmed to interpolate the data at rates of4x to 252x. The AD9857 is interfaced to the DSK using an Altera Cyclone FPGA. The FPGAprovides queuing of the I/Q data, and the

The circuit remembers which of the two input variables, S or R, was most recently a 1,by recording on the output variable, Q, a 1 if it was S or a 0 if it was R. By realizing that this SRlatch, the most fundamental memory circuit in any static memory device, is actually anasynchronous finite state machine, one realizes the fundamental nature of this topic.

andWi-Fi systems have to overcome to provide acceptable service, even in more or less benignenvironments.Finally, it is important to note that the I and Q signals can be captured and stored through minormodifications to the LabView VI’s. An instructive exercise is to have the students demodulate areal-world signal using Matlab. For example, suppose an FM signal is captured and stored in aMatlab vector “s” such that the in-phase and quadrature components are represented as the realand imaginary parts. We can extract the signal envelope as “envelope = abs(s)” and theinstantaneous phase as “theta = angle(s)”. Since the FM phase is the integral of the messagesignal, the message signal can be extracted by differentiating the phase using “m = diff
