 A demux is conceptually similar to a railroad switching system, this time the one that the trains
 use entering a station. A train coming from a railroad is routed to a specific track to

-In my mind a Mux is similar to a track switch on a railroad. More specifically the switching system for the trains leaving a station. There are plenty of platforms in the station and the switches must be set up for the departing train to guarantee the routing to the railroad to the next station

		+	To test this circuit plug in 4 leds to the output lines and connect four buttons to its inputs.
		+	If you push and release the button connected to in0, out00 will turn on and off in the same manner. Now push and keep pressed the button connected to c0. The value of in0 will be copied on out01, I mean now the led on out01 instead of out00.
		+	The same experiment can be done using in1 and c1 as inputs and out10, out11 as outputs.
		+
		+	If you have two breadboards (or a friend has one) and you have both build this circuit it is possible to plug the two boards together and get a 2 control bits (four data outputs) demultiplexer (plus a spare 1bit demux).
		+	Connect out00 and out01 of the first board to in0 and in1 of the second and
		+	connect c0 and c1 together.
		+	The input of in0 of the first board will be routed on out00, out01, out10 and out11 depending on
		+	the value given to in0 of the first board and in0-in1 of the second.
		+
		+	The next chapter will describe in details how the circuits implemented on several breadboard can be connected to obtain more complex circuits.
