Google has 300 servers around the world. Servers are failing about 1 every month. How would you go about debugging the failure?? That's great, good answer. The failure is actually random. Nothing you've tried is able to duplicate the failure exactly the same. How do you approach this?? Another good answer. Now, what do you think is actually the cause of these failures?

Tell me the waveform output at probe 1 and 2. The problem consist of a dc 5V going to a 5V sine wave input going to a capacitor. This system is then going into a 12V dc input with a two 1K resistor in parallel. This feeds into a emitter side of a transistor with a +-3V toggle as a base. The collector is going to ground. The two probe points is (1) before the cap and (2) before the emitter.
