2. A thermal couple measures a temperature range between 0°C to 500°C. It is required that the measurement system be able to distinguish a 0.5°C temperature change at its output. Assuming a linear relationship between the thermal couple's outputs and temperature changes, how many bits would you need your A/D converter to have?

To a measurement range of -4 to 6 V, apply a 4-bit analog-to-digital converter.  a- Identify the assigned voltages to each of the bins. b- Determine the voltage that will be assigned to a measurement reading -3.25 V. Calculate the percentage ADC error. c- Determine the voltage that will be assigned to a measurement reading 4.11 V. Calculate the percentage ADC error.
