DEMO 1 - Slide the mouse over the gray rectangles to see the relationship between the one-sided and two-sided spectral plots for the amplitude of the sinusoid x(t).
DEMO 2 - Slide the mouse over the gray rectangles to see the relationship between the one-sided and two-sided spectral plots for the phase of the sinusoid x(t).
DEMO 3 - Slide the mouse over the gray rectangles to see the two-sided spectral plots of x(t) equal to a sum of sinusoids.
