 Consider a temperature sensor whose analogue voltage output is connected to

Consider a temperature sensor whose analogue voltage output is connected to an analogue-to-digital converter (ADC). The sensor can measure temperatures within the range 0-25 degrees Celsius with a resolution of 0.1 degrees Celsius. The sensor's output varies between (0.7 Vcc) and (0.45 Vcc) over this temperature range, where (0-Vcc) volts is the supply voltage range for both the temperature sensor and the ADC. (i) Describe two different approaches for interfacing this temperature sensor to the ADC. Be sure to explain the benefits and drawbacks of each approach. [4 marks] (ii) Assume that the ADC uses a 4-bit successive approximation register (SAR) converter. What would be the value of the ADC's digital output sample if the measured temperature was equivalent to the sensor's minimum output voltage? Be sure to show your workings and to explain your approach. [5 marks] Calculate the address space associated with a 32-bit address bus if memory is organised in 8-bit words. Subsequently, compare the speed of an 8-bit processor and a 16-bit processor in calculating the summation "64 + 164" when these two numbers are presented as unsigned integers. Be sure to show your workings. [3 marks] Consider a temperature sensor whose analogue voltage output is connected to an analogue-to-digital converter (ADC).
