Electrical Engineering

An accelerometer with a charge sensitivity of 83 pC/g and acapacitance of 1000pF is connected
to a voltage follower with an input connector capacitance of 15pF(in parallel with the cable
capacitance), a 10,000pF blocking capacitor and a 100M? resistance.A 3m long cable with a
capacitance of 312pF connects the accelerometer and the voltagefollower. Determine:
1. the schematic of the instrument.
2. the instrument’s voltage sensitivity in mV/g.
3. the minimum sampling frequency required to sample thedata.
4.The gain required in order that the instrument can measure theacceleration from 0.01g to 1g using a 12-bit ±5V A/D converter.
