Suppose that a TM4C123 is used with a pressure sensor to monitor the pressure exerted on a valve. The pressure sensor measures pressure in the range 50.0 psi (pounds per square inch) to 550.0 psi and converts it proportionally (i.e. linearly) to an electrical signal in the voltage range from 0V to 2.5V. Assume the maximum input voltage used for the TM4C123 ADC is 5V. a. Suppose the gas pressure is 250.0 psi. [5 pts] i) What is the voltage level at the sensor's output? Note: the minimum input value for the pressure sensor is not zero. ii) What is the digital reading from the TM4C123 ADC after conversion? For this question, use M 2" steps (or bins) on the digital scale. Note: The ADC input voltage range is defined by its maximum value (not the sensor's range) If the digital reading was 225 (decimal), what is the range of possible analog input voltage values just read?
