4-Dipole Array Simulations demonstrates the pattern of an array of 4 elements, pointing in the z direction and placed along the x axis with equal spacing d=0.5 wavelength. The program has also shown the pattern of the array as the progressive phase

Plot the power‐spectrum of the signal at 30.34 seconds. Use an analysis window of 23 ms. Your plot should be labeled as dB in the y‐axis and frequency (Hz) for the x‐axis. Comment very briefly on the spectral characteristic of the signal.
