A compact disk (CD) stores music (an analog signal) in a digital format. How is this done? How is the digital data reconverted to the music you hear? Given that audible frequencies range from 20 Hz to 20 kHz, what is an appropriate sampling frequency? For this sampling rate, how many bits must be stored on a CD to produce 45 minutes of listening pleasure, assuming the music is stored uncompressed (e.g., as a WAV file and not as an MP3 file)? Assume just the raw data is stored, without the sophisticated error correction and compensation schemes described in Internet Link 8.5.

Answer the following questions, to test your understanding of sampling frequency and bit depth. 1. You are part of new automobile design team, and are responsible for designing the sensor data collection system. The specification of the data collection system is that is must be capable of receiving data with a resolution down to 0.1% of full scale (1 part in 1000) for any given sensor. For example, suppose the driver pushes the gas pedal, the motion of which is read by an electronic sensor such that the range of motion is defined from 0 (not pressed) to 1 (fully pressed). If you want 0.1 % accuracy, you need 1000 possible data values between 0 and 1. How many bits do you need to represent data to 0.1% accuracy? Insert a picture of your work.

O You are running an industrial research study together with your project team to improve energy efficiency in a combustion process. The purpose of the research is to identify the optimum air-fuel ratio for the combustion process in a boiler under varying conditions of air supply and quality of fuel. The study would involve design of experiments, data collection and analysis, simulation of the different variables and validation of the optimum parameters. There is a lot of pressure to improve the energy efficiency as there is a forecast of fuel price rise in the forthcoming month. Based on the CRPE code of ethics, explain two critical precautions which the engineers have to consider before implementation of the data collection process for the industrial experiment. to be taken during the Describe briefly five ethical measures experimentaldata collection in order to ensure validity of results. Explain two precautions to be taken during the report writing on the research study carried out…

You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the Ti-6Al-4V…
