For all problems, you may use any 5% resistors in Appendix J ranging between 2.2 N and 1 M2. You may use capacitance with multiples of 1.0, 1.2, 1.3, 1.4,1.5,

1.8, 2.0, 2.2, 2.5, 2.7, 3.9, 3.3, 3.9, 4.3, 4.7, 5.0, 5.6, 6.6, 6.8, 7.5, 8,2 and 9.4 ranging between 0.10 pf and 470 uF. Assume all diode drops are 0.7 V. If a transistor is operating in saturation, assume CE = 0.2. Assume ß= 100 for all transistors. Show your work for all problems. A value that just appears with no calculation or explanation does not exist (for purposes of grading). 1. Design a power supply that will convert a 120 V(rms) 60 Hz household supply through a 12-to-1 step-down transformer and a bridge rectifier to+12 V(dc) with a maximum ripple of ±1 V. What is the PIV? What percentage of the cycle is the bridge conducting?
