An analog accelerometer produces a continuous voltage that is proportional to acceleration in gravitational units or g. Figure P4–74 shows the characteristics of the accelerometer in question. The black curve is the actual characteristics;

the colored curve is an acceptable linearized model.

Design an instrumentation system that will output 0 V for

1 g and 5 V for 1.5 g. Note that this accelerometer has an output resistance of 32 kV
