Unformatted text preview: is z 90% n ), evaluate the uncertainty for each sensor in C. 3. With the current system, which sensor gives a more precise measurement and will the final uncertainty be less than 0.25C (Uncertainty from quantization is max rounding error, Q/2, and is independent from Uncertainty from problem 2)? ME365 POSTLAB 5A Fall 2011 4. We are considering upgrading the data acquisition systems ADC to a 16 bit system, but we would like to know if we can save expense by reducing the input range of the ADC instead. If we reduce the input span to 40 mV, will the error from quantization be less than the uncertainty from the noise (due to n ) for both sensors? 5. The temperatures we are measuring are slowly varying (which is why we are only considering the static response), so we can possibly filter/average the sensor signal and minimize the effects of random noise. For our future reference, which sensor would be best if experiments confirm the effects of noise can be made negligible?...
