BME 311 Network Theory Final Exam (time: 180 minutes, total score 100 points +10 bonus points) May 10, 2006, 2-5 pm at NOA 1.102 Page 1 of 11 (c) John X.J. Zhang, UT Austin Name:_______________________ Score:_______________ Question 1 (10 points) The periodic waveform f(t) shown has the following repetitive pattern: 5V for 10 μ sec, and -5 V for 2 μ sec. (a) What is the average value of f(t) ? (b) What is the average value of f 2 (t) ? (c) Setup the integral and find the RMS value of the waveform. Hint: Given a periodic function, f(t), its RMS value (or the effective value) is given by: = T RMS dt t f T F 0 2 ) ( 1 , where T is the period of function f(t) . f(t)

Zhang, UT Austin Question 2 (10 points) The frequency of the 10 V (amplitude) voltage source in the circuit below is adjustable. When frequency f =0, no current flows because the capacitor is an open circuit at DC. As f is slowly increased from zero, current begins to flow. Assuming that the voltage source amplitude remains 10 V, use phasor analysis to find a frequency f (in Hertz) where the current I amplitude equals 0.707 A. I
