A pressure sensor outputs 2.5 mV/kPa, but there is 60-Hz noise of a steady peak 55 mV on the line. Pressure in the range 0.0 to 70 kPa must be converted by an ADC and presented to a computer. The resolution must be at least 0.2 kPa.
a. Design a system of filter, signal-conditioning, and ADC specifications to satisfy this requirement.
b. Suppose the pressure suddenly changed from 20 to 50 kPa. How long would it be before the ADC presented the correct digital signal for this pressure to the computer?
