THINGS TO NOTICE
When the transmitted message is all zeroes, then there was no error during transmission.When the remainder is not all zeroes, an error occurred and the original message can not be recovered.
We do not pad with zeroes before division, nor do we stip bits before division.
THINGS TO TRY
Set the slow-motion slider to about .2 seconds (or slower) and press the step button several times. Watch the demonstration of each step.Set the slow-motion slider to about .2 seconds and press the go button. Watch the entire demonstration.
Do each step by hand, then press step to check your work.
HomeApplets 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.
