You are in charge of the IT division for a company that has 1,048,576 customers. Your boss asks you to decide between buying a database system from Vendor A or Vendor B. Both systems are the same price but Vendor B’s computer (computers are included in each system) has hardware that is 1000 times faster than that provided by vendor A. However, Vendor A’s system is based on an algorithm that returns a response to a query in time proportional to 10nlog2n machine operations where n is the number of customers in the database while Vendor B’s system is based on an algorithm that returns a response to a query in time proportional to 10n2 machine operations. Vendor A’s computer has a speed of 1 nanosecond (=10-9 seconds) per operation.

How long (in seconds, rounded correctly to three decimal places to the right of the decimal) would Vendor A’s system take to return a response to a query based on your current number of customers? seconds

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx,fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx,fs) does automatic scaling and then calls sound(xx,fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
