2.1 What do you understand by quantization of analog signals? Can we carry out analog to digital conversion without any quantization? Why? factors govern number of quantization levels?

2.2 An Electric Vehicle traction motor winding temperature ranges from -30 to 300 Deg C. The same needs to be measured with 1 Deg C accuracy. Prove that an 8-bit ADC will not be sufficient for the measurement

2.3 An Engine Coolant temperature sensor is delivering a temperature reading of -20 Deg temperature. The outside ambient temperature is also -20Deg C. Would you be able to conclude if the sensor is faulty or not? How? If so, will it be a failure or a type B failure? Explain your answer

2.4 Is it possible to identify an aggressive driver from a disciplined driver using telematics data? Explain your answer. A driver blames chaotic traffic to justify his behavior. How can his claim be independently verified?
