Project Proposal.

In this project we will implement a java applet that demonstrates through animation the behavior of a transmission line which is is terminated with its characteristic impedance, subject to real line attenuation and uses a local average stategy to detect collisions of Ethernet pulses. Referring to the virtual textbook chapter and any other reference materials you need, develop a good understanding of the computation of the voltage and current waves that traverse a line as a function of characteristic line impedance and terminations.

The Java applet allows the user to enter the line length and attenuation of the line in db/meter and a threshold value for collision detection. The applet should now compute the average of ten received pulses at the center of the cable from one transmitter and from two transmitters. It then displays the collision decision based on the calculations and the given threshold.
