- Figure 4 In Appendix Shows The Spectrum Plot Of A Signal X N Plotted With The Matlab Code Fs 1000 T 0 1 Fs 1 5 1 (86.92 KiB) Viewed 27 times
Figure 4 (in Appendix) shows the spectrum plot of a signal x(n) plotted with the Matlab code, fs = 1000; t = 0:1/fs:1.5-1/fs; X = ? X = fft (x); Xmag abs (X) ; = figure (), plot (Xmag) Determine the equation of x(n) that was used to generate the plot in Figure 4 provided with the information below: X(bin) X(31) X(91) X(226) fft(x) 1.4701e+03 +2.9800e+02i 3.5825e+03 1.1082e+03i -1.6591e+03 +1.5198e+03i
