INTRODUCTION TO SPECTRAL PLOTS
| LAST DEMOS | NEXT DEMOS | TABLE OF CONTENTS |
DEMO 1 - Slide the mouse over the gray rectangles to see how the amplitude of the sinusoid affects its spectral plot.

DEMO 2 - Slide the mouse over the gray rectangles to see how the phase of the sinusoid affects its spectral plot.

DEMO 3 - Slide the mouse over the gray rectangles to see how the frequency of the sinusoid affects its spectral plot.

DEMO 4 - Slide the mouse over the gray rectangles to see how adding sinusoids to a constant affects the signal v(t) and its spectral plot.

DEMO 5 - Slide the mouse over the gray rectangle to see the spectral plot of v(t).
