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.

4. Signal conditioning element basically takes the output of the sensing element and converts it into a form more suitable for further processing, usually in the form of a DC voltage, DC current or variable frequency AC voltage. The output of the sensing element is usually too small to operate an indicator or a recorder. Therefore, it is suitably processed and modified in the signal conditioning element so as to obtain the output in the desired form that is amplify the signal and filtering the unwanted signal. i. Describe the aliasing phenomenon. ii. Suggest a solution to minimize the effect of aliasing.
