Problem 1: Design a system to convert temperature, x [150 K , 300 K], to a floating point number, temp = H ( x )= x/ K, using the new Transducer Z. An algebraic model function for the new Transducer Z is not available but a lookup table, HtZ ,is . Tab le HtZ is a 4096-element array which stores the resistance of the sensor in ohms from a temperature of 100 K ( HtZ[0]=870 )to 400 K ( HtZ[4095]=6500 ). (The temperature range covered by the lookup table is larger than is needed for this problem.) The relationship between the array index and temperature is linear. (The relationship between temperature and resistance is not linear.) An inverse table, HtZi is also available; element zero, HtZi[0]=100 , gives the temperature in Kelvins when the resistance is 870 Ω and
