Sampling a Phasor
A phasor is a rotating vector. In this applet, we periodically sample the y-value of the vector and display it.
- Move the fader slightly to the right until you see a curve being drawn.
- Dont 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.
