D Question 8 1. AK-type thermocouple as shown in the figure below generates a voltage that is proportional to temperature. Typically, the slope of the voltage vs. temperature line is about 41μV/C (micro-volts per degrees Celsius). Assume that the thermocouple is directly connected to a 20-bit ADC that has a range of 0-5 volts D.C. (You'll find out next week we don't do it this way, and that makes for a reason to come back to class.) Calculate the smallest change in temperature that results in a change of on bit of the ADC. About 3 degrees Celcius O About 1 degree Celcius About 20 degrees Celcius About 0.1 degrees Celcius
