Sampling a Phasor

A phasor is a rotating vector. In this applet, we periodically sample the y-value of the vector and display it.

To do:

  • Move the fader slightly to the right until you see a curve being drawn.
  • Don’t move the fader for a while. What kind of curve do you see?
  • Move the fader farther to the right. Notice how the phasor spins faster and the wavelength of the signal becomes shorter.
