Consider the following method. An 11-line code segment reads as follows. Line 1: public static boolean mystery, open parenthesis, String str, close parenthesis.
Line 2: open brace.
Line 3: String temp equals, open double quote, close double quote, semicolon.
Line 4: blank.
Line 5: for, open parenthesis, int k equals str, dot, length, open parenthesis, close parenthesis, semicolon, k greater than 0, semicolon, k minus, minus, close parenthesis.
Line 6: open brace.
Line 7: temp equals temp plus str, dot, substring, open parenthesis, k minus 1 comma k, close parenthesis, semicolon.
Line 8: close brace.
Line 9: blank.
Line 10: return temp, dot, equals, open parenthesis, str, close parenthesis, semicolon.
Line 11: close brace.

Required:

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
