Write a Java program that constructs a Graphical User Interface using JavaFX. Your GUI should contain two sets of four buttons for a text, "Start", "Stop", "Clear" and "Change the text". The first three buttons will be organized horizontally, and there should be a textfield where a user can enter a text, and the button "Change the text" should be under the textfield (see the snapshot of the GUI). Under the button "Change the text", there should be a label "Rate", then below it, there will be a slider that a user can use to change the rate (speed) of a text. Right hand side of the buttons, a textfield, a label and a slider there are panes, each pane showing a text with their initial color. The top should be red and the bottom one should be blue with their background black. The picture below shows a snap shot of the GUI. Each pane should keep printing the given text. (The size of the applet here is approximately 550 X 400).

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
