Question 4 a) Identify and briefly describe TWO suitable sensors which could be used to measure temperature and TWO sensors which would be suitable to measure pressure. b) A linear temperature sensor produces an output voltage of 0-0.5 V when the temperature varies in the range 0-100°C. Calculate its sensitivity. c) Design a suitable amplifier circuit, based on an idealised operational amplifier which will produce an output voltage in the range 0-5 V for the sensor from Part b). Your answer should include identification of the amplifier type chosen, circuit diagram, component selection and calculations. A 12-bit analogue to digital converter (ADC) is to connected to the output of the amplifier from Part c), also having an input voltage range from 0-5 V. i) Calculate the number of discrete input levels which can be recognised. Calculate the input resolution of the ADC in volts. d) ii)
