A DAS has an ADC of 8 bits with a 0- to 2.5-V range of input for 00H to FFH output (i.e., FEH to FFH occurs at 2.50 V). Inputs are temperature from to scaled at, pressure from 1 to 100 psi scaled at 100 mV/psi, and flow from 30 to 90 gal/min scaled at 150 mV/(gal/min).
Develop a block diagram of the required signal conditioning so that each of these can be connected to the DAS and so that the indicated variable range corresponds to 00H to FFH.
Specify the resolution of each in terms of the change in each variable that corresponds to an LSB change in the ADC output.
