Attached the graphs of XSC1 and XSC2 to the end of this work sheet. Describe in the space below, qualitatively what each graph indicates. Do these graphs meet your expectations based on what you learned in Physics 260? Why or why not? (5 pts) 2. From these graphs, estimate the time that waveform for each gets to 68% of its final value. (10 pts) a. XSC1 takes ________________ seconds to reach 68% of its final value. b. XSC2 takes _________________ seconds to reach 68% of its final value. 3. Calculate the RC time constant. Fill out the table below: (10 pts) Scope Simulation Seconds to reach 68% RC time constant for Circui 2 Percent Difference XSC1 XSC2 4. Should there be any difference between the RC time constant and the risetime/falltime values measured for XSC1 and XSC2? (5 pts)
