HOW TO USE IT
The setup button generates a random bit pattern using the number of bits specified by the number-of-digits slider.The random button generates random settings for the number-of-digits slider, parity choice box, and placement choice box. Then a random bit pattern is generated.
The step button demonstrates the next step, and then stops so you can take notes. This is useful when you are first learning the method.
The go button does every remaining step, at a speed determined by the slow-motion slider. This is useful when you do not need to take notes between each step.
The show-again button starts the exact problem from the beginning. You may then click either the step button or the go button to see the same demonstration.
The slow-motion slider is an easy way to adjust the speed of the display. Set it to zero if you want to show the final result as quickly as possible. 0.5 is a good setting for most purposes.
The number-of-digits slider specifies the number of bits for the random bit pattern generated when the setup button is pushed.
The quiz button will generate a random bit pattern and ask the user how it would be sent using a specified parity.
The parity choice box specifies whether even or odd parity will be demonstrated.
The placement choice box specifies whether the parity bit added at the end will be placed at the far right or the far left of the other bits.
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.
