Choose Research Topics Yourself:no matter the one list in the research topic section,or you design your own.Save your data,and take detail record of the procedure. 9 Copy all files in your private folder to your own media for your experimental report after class. Cautions: 1.Read the manuals and instruction carefully beforehand 2.The total number of points N and the time interval dT are import for FFT result.Once you choose the proper N and dT,the curve in the UAl window would smooth. 3 Make sure you put the switch to="positon,when you connect the microphone in. 4. Floppy disks are used to copy the experimental data.Ask your teacher to format them. Discussions 1.If change the connection of the oscillation circuit,or change initial conditions,does the frequency spectrum change? 2.Explain what will be,if choose different d'T,or N,where dT is the sampling time interval,and N is the total sampling points. 3.Explain why there have two peaks in the spectrum of the coupled RLC circuit. 4.Are there any advantages or disadvantages of computer aided data acquisition and processing system? 5. All phenomena appearing in your experiment should be analyzed.If possible,make a simple order-of-magnitude analysis,and/or verify your points experimentally. 2222 (as shown in fig below). Fig.4.
