SYSTEM ENGINEERING CSE401 Wednesday, May 09, 2018 Q5. For the system given below, Assume room temperature and that 14-watt fixed composition resistors are used. Assume that failure rates of: BJT is 1.5 x 10-3 failures / 10 hours , Rc is 2.5 x 10-3 failures / 10 hours and, RB is 7.5 x 10 failures / 10 hours [5 Marks] Find out: a) Type of system_ (Parallel/ Series ) [0.5 Marks ] b) Total Failure rate (as ) [2.5 Marks] c) the overall system reliability in 20 years, and [1.5 Marks] d) the MTTF [0.5 Marks] V = 5V R = 100 V = 5 Vor OV = V V R = 10k V,=0 or 510-W 2N3904
