At left, one sees a modulated signal being generated as a sum of the
carrier (green), and lower (red) and upper (blue) sideband frequencies.
Each carrier/sideband component is represented by a rotating arrow ("phasor"),
of which the length indicates its amplitude and the angle its phase;
the vertical component of a phasor is the component's current value.
At right, these signals are shown propagating in space, both the individual sideband components and their sum.
Controls at the bottom allow setting the signal and modulation frequencies, modulation format, and propagation speed and dispersion.
