Question: A Cal Poly Pomona Mechanical Engineering student mounts an accelerometer having a sensitivity of ( 2 . 8 mathrm { mV } /

A Cal Poly Pomona Mechanical Engineering student mounts an accelerometer having a sensitivity of \(2.8\mathrm{mV}/\mathrm{g}\) to one of Cal Poly's Mini-Baja front end struts. He has built a data acquisition system (DAS) using an operational amplifier, a passive low-pass RC filter, and an \(\mathrm{A}/\mathrm{D}\) converter having 4 bits and a full-scale excitation of 10 Volts. He is sampling the data at a rate of 5000 Hz . On the memory of his DAS, the binary value of 0111 corresponds to the magnitude of the voltage measured by the accelerometer. Unfortunately, his filter attenuates the signal by 5 dB . If the Op-Amp gain is set at 1000, determine/address the following:
(a) Neatly and accurately sketch a block/flow diagram of the DAS showing all major elements as described above
(b) Compute the voltage at each stage in the DAS and clearly label the diagram of part (a) with these computed voltage values
(c) Roughly, how many g's does the value of 0111 at the data acquisition board correspond to?
