you and your friend. However, it would be too expensive to directly wire every telephone inNorth America to every telephone in Asia. Laying one wired connection across the PacificOcean is expensive enough.Have a look at the animation at system.gif. Here we see a solution for wiring telephones in North America to telephones inAsia: have one wire between the continents, and connect telephones from the two continentsto either end of this one wire, as needed for conversations.(This technique is known astime-division multiplexing.)TODO (pre-lab): In the animation, five conversations are being connected.Draw what it would look like if six conversations were being connected.The connection scheme in the animation uses a circuit called ademultiplexerto undothe effect of the multiplexer.The multiplexer selects the caller’s signal and passes it tothe demultiplexer, which then selects the appropriate receiver to send the signal to, thusconnecting the two friends.A 1-to-2 demultiplexer has two inputs:s, analogous tos(select) in our multiplexer, andy, an input wire.It produces two outputs:x0andx1, the demultiplexed signals. It works like this:•Whens= 0,x0outputs the value ofy, andx1outputs LOW.
