Q3 Thermistors are electronic components whose resistances change with temperature, When thermistors are used to measure temperature, it is important to calibrate the resistance-temperature (RT) curve. (a) List the key steps to calibrate a thermistor's RT curve. (5 marks) (b) TTC05104 is a typical thermistor from the market. Suppose it has a log-linear model for its RT curve: log 10 y = k * x + b where k is the gain, b is the offset, x is the temprature and y is the resistance. Estimate k and b using the Least Squared Error method with the data shown in Table Q3. (15 marks) (c) Using L2 norm, measure the error in (b). (5 marks) Table Q3. Data set for TTC05104 calibration Index Temperature (C) Resistance (ko) 1 30.0 80.0 2 40.0 50.0 3 60.0 21.0 4 80.0 10.0 TOTAL FOR Q3: 25 marks
