Consider the following class. public class LightSequence { // attributes not shown /** The parameter seq is the initial sequence used for * the light display / public LightSequence(String seq) { / implementation not shown */ } /** Inserts the string segment in the current sequence, * starting at the index ind. Returns the new sequence. / public String insertSegment(String segment, int ind) { / implementation not shown */ } /** Updates the sequence to the value in seq / public void changeSequence(String seq) { / implementation not shown */ } /** Uses the current sequence to turn the light on and off * for the show / public void display() { / implementation not shown */ } } Question 1 (a) Write a statement to create a LightSequence object gradShow that has the initial light sequence "0101 0101 0101". Write the statement below. Question 2 (b) Write a statement that will call the display method to display the light sequence for the gradShow object. Write the statement below. Question 3 (c) Write a statement that will be used to update the gradShow light sequence to "0011 0011 0011". Write the statement below. Question 4 (d) Write a code segment that will call the insertSegment method to insert the segment "1111 1111" in the current sequence for gradShow at index 4. The resulting sequence will be stored in the string resultSeq. Write the code segment below. Question 5 (e) Assume that the string oldSeq has been properly declared and initialized. Write a code segment that will remove the first occurrence of the string segment from oldSeq and store it the string newSeq. Consider the following examples. If oldSeq is "1100000111" and segment is "11", then "00000111" should be stored in newSeq. If oldSeq is "0000011" and segment is "11", then "00000" should be stored in newSeq. If oldSeq is "1100000111" and segment is "00", then "11000111" should be stored in newSeq. If oldSeq is "11111" and segment is "00", then "11111" should be stored in newSeq. Write the code segment below. Your code segment should meet all specifications and conform to the examples. Question 6 (f) Two lights will be arranged on a two-dimensional plane. The vertical distance between the two lights is stored in the double variable a. The horizontal distance between the two lights is stored in the double variable b. The straight-line distance between the two lights is given by the formula a2+b2−−−−−−√. Write a code segment that prints the straight-line distance between the two lights according to the formula above.

Now youâ€™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
