Figure out this value and set the delta t at least 3 times smaller than this value and calculated yl(t) and y20). Increase the step size (delta t and recalculate yl() and y2(t). See the difference. Calculate Fourier Transform of yl(t and y20t using fft and plot your results. Using frequency as the x axis data and amplitude as the y axis data. Also, plot the phase, too. f[0:1Mength(yl): 1/2] (1/ delta t) ama 1 fft(yl) figure: plot (f abs(am101:length(f)), Use function of abs to calculate the amplitude and angle to calculate phase.](http://img.homeworklib.com/questions/c0e89ca0-5395-11eb-8093-63e621741d93.png?x-oss-process=image/resize,w_560)

You are given a finite step function xt=-1 0<t<4 1 4<t<8. Hand calculate the FS coefficients of x(t) by assuming half- range expansion, for each case below. Modify the code below to approximate x(t) by cosine series only (This is even-half range expansion). Modify the below code and plot the approximation showing its steps changing by included number of FS terms in the approximation.
