THINGS TO NOTICE

Some encoding schemes are prone to loss of synchronization. That is, some bit patterns will produce an encoding where the signal stays at the same voltage level for multiple time slices. Which encoding schemes might have this problem? Which never do?

If the average voltage is not zero, then there is a DC component to the signal. This can cause signal distortion and possibly even damage equipment. Which encoding schemes might have this problem? Which never do?

Which encoding schemes use the fewest number of transitions? Which use the greatest?

THINGS TO TRY

Set slow-motion to 0.3, click random, and then click go.

Set the encoding choice box to the type of encoding you want to drill, then click setup. Attempt one bit at a time on paper, and then click the step button to check that you did that bit correctly.

Applets on this website were written by Teresa Carrigan in 2004, for use in computer science courses at Blackburn College, with the exception of the Fireworks applet. The applets made with NetLogo require Java 1.4.1 or higher to run. The applets made with NetBeans require Java 1.4.2 or higher to run. Applets might not run on Windows 95 or Mac OS 8 or 9. You may obtain the latest Java plugin from Sun's Java site.
