Homework Set 2 Out September 1 , 2011 Due September 8, 2011 Problem No. 1 In this question two analog to digital converters (ADC) will be considered. The information about these ADC’s are given in the following table: ADC Number of bits Nominal Range ADC1: 8 bits 0 to 10 volts ADC2: 12 bits -10 to +10 volts (a) Determine the output code (decimal integer) for both of the ADCs for the given input voltages, assuming positive codes only. i. -3.5 volts ii. 2.35 volts iii. 11.35 volts (b) ADC1 produced the follow output code (1110 0010) 2 . What is the range of input voltages that could produce this code, assuming positive codes only? (c) ADC2 produced the following output code (0000 1110 0010) 2 . What is the range of input voltages that could produce this code, assuming positive codes only? (d) Determine the resolution of each ADC. (e) If ADC2 is utilized to measure the output of a sensor modeled by the following calibration line: V (3.23 D 0.5) volts , where V is in volts and D is in mm. What the resolution of this measurement system?
