Assuming D=0.6, determine the ratio Vo/Vin QUESTION 7 In the previous question, determine IL/Io. QUESTION 8 Determine the RMS value of the following waveform (first do something about the second and 3rd terms). v(t) = 3 + 10cos(wt) + 5 sin(wt) + 4 cos(3wt) + 2sin(7wt-30) QUESTION 9 Consider the following signal: Starts at the origin. Linearly decreases to -1 by T/6. Remains at -1 until T/3. Then linearly increases to 1 by 2T/3. Remains at 1 for another T/6, and then decreases linearly to 0 at T. T is the period. Solve for a0 QUESTION 10 For the previous question, solve for a5 QUESTION 11 From Question 9, solve for b5. QUESTION 12 From Question 9, solve the RMS value of the fundamental component.
