DEMO 1 - Slide the mouse over the gray rectangles to see the spectral components of the periodic signal x(t).
DEMO 2 - Slide the mouse over the gray rectangles to see what happens to the spectral plot of the output y(t) of the bandpass filter as the center frequency is increased.
DEMO 3 - Slide the mouse over the gray rectangles to see what happens to the spectral plot of the output y(t) of the lowpass filter as the passband is increased.
DEMO 4 - Slide the mouse over the gray rectangles to see what happens to y(t) and its spectral plot as the passband of the lowpass filter is increased.
