The pdf<br /> diagramming the setups are displayed below.<br /> <br /> The following is a schematic with the data coming in the top Transistor.<br /> [[File:limit_on_top.gif|center|alt=A schematic]]<br /> The following is the simulation of the data.<br /> [[File:limit_on_top_graph.gif|center|alt=A graph]]<br /> You can see that some of the data is limited by the bottom resistor so this is not<br /> as good as the other way of which the simulation is done below.<br /> [[File:limit_on_bottom_circ.gif|center|alt=A schematic]]<br /> This is the Graph of the simulation, you can see that the data is passed in a better<br /> range and that the wave form of the slower wave data is taken from the faster data.<br /> [[File:limit_on_bottom.gif|center|alt=A graph]]<br /> There is still some distortion at the bottom of the graph but overall I think this passes better<br /> data than putting the oscillator on the top. If the transistors were biased<br /> better, I think that the data would show a little better.</div>
