The highway department wishes to study the roughness of certain highways. For this purpose, a vehicle is instrumented with a down looking sonar ranging unit and the associated electronics and data recording equipment. The truck moves at 50 mph and road height variations are thereby converted to a continuous time signal. The sonar spot is 3 inches in diameter, so roughness at smaller scales is lost. Of course, the vehicle shock-absorber/spring system acts as a high pass filter, so the really low frequencies are lost. The output voltage of the sonar unit is analog with voltages in the range of 0 to 100 mV. The sonar unit is followed by a low-pass filter, an amplifier, a sample and hold circuit, and an 8-bit ADC that requires a positive input voltage in the range of 0 to 5 V. The output of the ADC goes into a computer, which actively controls the sample and hold circuit and the ADC. A) What would be an appropriate cutoff frequency for the filter such that noise outside the data spectrum is eliminated? See 5.8. B) Desing the amplifier. Assume an input impedance of 1 KΩ and an ideal op amp. C) What is the minimum sampling rate for the system to record all the data? See 6.2. D) What voltage difference does 1 bit represent at the output of the ADC?
