Recursive backtracking: Suppose I want to burn some songs onto a 650MB CD (some people still do!) and I have a list of song tracks of various sizes. I want to fill up as much of my CD as I can. I can use a recursive backtracking strategy to find a subset of the song tracks that optimally fills my CD (that is, with the least space left unfilled). You should recognise this problem as a version of the Knapsack...
(a) In a recording studio, a particular brand of compact disk (CD) digital player has the capability of converting 16-bit signals from a CD into their equivalent analog values. Determine the: (i) largest and smallest Hex values that can be used in the CD player. (ii) different analog values that can be represented by the system.
The surface of a compact disk (CD) behaves as a kind of diffraction grating. When light is reflected from the surface, each of the closely spaced ridges on a CD behaves as the source of a spherical light wave. Except for the fact that light is reflected rather than transmitted, the effect is the same as for the transmission gratings described in the text; that is, one sees a spectrum of colors (see figure below). Suppose a beam of sunlight...

Suppose there are 29 songs in your itunes account, and you would like to make a playlist. 1. You would like to choose 11 different songs for your playlist. How many ways are there to create this playlist, where order in which you select songs matters? 2. Suppose you always use the random play function so that order in which you pick the songs on the playlist does not matter. How many ways are there to create a group of...
A certain CD ROM disk can store 600 megabytes of information. If an average word requires 9.0 bytes of storage, how many words can be stored on one disk? 05.4 × 109 words O 6.7 x 107 words 021x107 words 02.0×109 words
18. (10 points) A 700-Mbyte CD is used to store PCM data. Suppose that a voice-frequency (VF) signal is sampled at 8 ksamples/sec and the encoded PCM is to have an average SNR of at least 30 dB. How many minutes of VF conversation (i.e. PCM data) can be stored on the hard disk?
