. VSA’s would be an ideal addition to any undergraduate communicationslaboratory because of their ability to investigate the many types of signals prevalent today.Unfortunately, most VSA’s are priced well beyond the budgets of typical undergraduate ECEdepartments. This paper describes a novel low-cost VSA that uses basic PC data acquisition(DAQ) cards to capture signals of interest and real-time processing of signals with LabVIEWand MATLAB. This VSA system provides a user interface that has much of the basicfunctionality of standard hardware VSAs, but with the limitation that bandwidth is constrainedby the sampling rate of the DAQ. The system provides real-time plots of I/Q constellations. Wedescribe the user interface as well as example

Synthesize digital logic and fixed–point signal processing systems using VHDL. 3. Design filters that are robust to quantization effects. 4. Design hardware filters using distributed arithmetic. 5. Optimize hardware filters given realistic design constraints using a variety of filter design tech- niques. 6. Design the hardware to implement an adaptive filter. 7. Describe the relevant theory and implementation of an adaptive filter. 8. Describe the trade–offs (including precision, accuracy, dynamic range, implementation size, and signal–to–noise ratio) between fixed

TCFFHRC and a fourth-place finish in the Navigation Challenge of the 2005 IGVC, naturally have built studentconfidence. The RST is divided into project groups, each focusing on a specific robot design.Every member of the RST chooses one or more projects and is expected to report regularly to theweekly RST seminar, which the second author supervises. In the fall of 2006, the team worked Page 12.336.3on four projects: (1) A new autonomous land vehicle (named Q). From 2000-2006 this group designed and competed with another IGVC robot, ALVIN. Q is an entirely new design based on an electric racing wheelchair. In the fall of 2006 the

well.Once they are comfortable with FSK, we have found they are far more ready to understand otherdigital communication topics. Note that CommDSK, also a part of winDSK6, allows students toexperiment in real-time with BPSK, QPSK, 8-PSK, 16-PSK, 8-QAM, and 16-QAM along withtopics such as bit shaping, I/Q imbalance, channel noise, etc.15We freely distribute the winDSK6 software for educational, non-profit use, and invite user sugges-tions for improvement.
