- I was running a production line for thin film optical fiilters for the verizon FIOS build out. The device had 27 layers and if the stress imparted was too high than the films would pop of, my production in line measurements were all within specification but we had massive failure, why? a) the in line specifications was too wide, the process distribution moved but was within specifications so product was moved on, but was actually prone to failure. The specifications upper and lower limited were modified with new failure data. b) the inline specification was too narrow c) Verizon FIOS showed to many bad movies d) the inline specifications was too narrow , the process distribution moved but was within specification so product was moved on but was actually prone to failure .arrow_forwardTasks Create a timing diagram for the following circuit schematic and the case that c changes from 0 to 1 (the other input values are: a = 0 and b = 0, and do not change): m Figure 1: Circuit Schematic Make sure to include all inputs (a, b, c), outputs (F, G, H) and the indicated inter- mediate values (k, 1, m, n) in your timing diagram. Answer the following questions: 1. What is the delay of the longest circuit path? 2. What is the delay of the shortest circuit path? Indicate the delays as number of gate delays. Make sure to consider the entire circuit for finding the shortest/longest circuit path. These delays are not tied to the specific input change that was indicated for the timing diagram and only depend on the number of gates between an input and an output.
