Examine your desktop computer, laptop, or cloud drive and total up your organizational points as described below: Count the icons on your desktop. If you have fewer than 20, award yourself 1 point. Check the root directory (Macintosh HD or Windows C:). Award yourself 1 point if there are only folders and no files there. Examine the folders listed under your user name. Give yourself 1 point if you can identify the kinds of files that each one contains. Open each of the folders listed under your user name. Award yourself 1 point if none of the folders is empty. Open the Documents folder. Award yourself 1 point if you have fewer than 100 files (not counting folders) listed there. If you use one set of folders for your personal data and another set of folders for school or work data, award yourself 1 point. Open the folder that contains most of your photos. Give yourself 1 point if the photos are organized into subfolders according to date, subject, or other criteria. Browse files on your storage device. If you don’t seem to have unnecessary duplicates, give yourself 1 point. If you can launch any program in fewer than 5 seconds, award yourself 1 point. If files and folders that you use frequently are in your Quick Access or Favorites list, add another point to your score.

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

For positive constants a and b, the force between two atoms in a molecule is given f(r) = −a r2 + b r3 , where r > 0 is the distance between the atoms. note: a and b are upper case letters. (a) find f '(r) = (b) find the critical point for f(r). r = (c) find f ''(r) = (d) find the value of r so that f ''(r) = 0.
