Question: a. With using MATLAB, plot the signals between (0,2) seconds with sampling frequency. a. With using MATLAB, plot the signals between (0,2) seconds with f.

a. With using MATLAB, plot the signals between (0,2) seconds with sampling frequency.

a. With using MATLAB, plot the signals between (0,2) seconds with f. = 1000 Hz sampling frequency. x [n] = COS ( 2710n x2 [n]=cos (2750) 13 [n]=COS (27150n) [Plot the signal by using "subplot", "figre", "plot", "grid on" commands] b. By using "fft", "fftshift" plot the two sided power spectrum. Horizontal axis must show frequency (Hz). Vertical axis must show the relation between power spectrum and magnitude of frequency spectrum) c. Calculate the discrete fourier transforms of the given signals using MATLAB codes. Also calculate the DFT with fft command and compare your results
