DEMO 1 - Slide the mouse over the gray rectangle to see how making the pulse x(t) narrower affects its Fourier Transform.
DEMO 2 - Slide the mouse over the gray rectangles to see what happens to the Fourier Transform of the unit pulse x(t) of area one as it morphs into an impulse.
DEMO 3 - Slide the mouse over the gray rectangles to see what happens to the Fourier Transform of the pulse x(t) as it morphs into a constant.
