interestedreader can download a sample lesson outline and associated PowerPoint slides.IntroductionFor the purpose of this paper, timing jitter is defined as “the phenomenon seen when a digitalwaveform’s transition appears before or after the expected time.”1 When jitter displaces thesignal’s transition so much that it happens in an adjacent clock cycle, the result is a data error onthe bus. Because of the high speeds and compact designs of today’s systems, jitter that used tobe negligible is now very significant, and can prevent a system from working correctly.1Today’s designers need the ability to analyze jitter, trace its root cause(s), and mitigate oreliminate the cause(s).In order to effectively analyze jitter, one must understand its nature, the

I have wanted our department to offer these classes or cover this material for some time.

When Motorola spin off their microprocessor division to Freescale Inc., 5 the68HC11 EVB became very hard to obtain. The alternative EVB made by Axiom is moreexpensive. 1 Another draw back is that the alternative board has limited functions as comparedto the original Motorola 68HC11 EVB.1,9 In order to extend the use of the 68HC11 EVB and keep

model rocket manufactured by QuestAerospacet5. A diagram of the rocket is shown in Appendix A at the end of this paper. Thisrocket was chosen because of its unique payload section which is separate from the parachutestowing area. In model rocketry the parachute is deployed by the, “Ejection charge” that isproduced by the rocket engine after the thrust charge is depleted. The ejection charge effectivelyforces the rocket stages to separate and propels the parachute(s) out of the storage chamber. Byhaving a separate payload section, the sensors can be shielded from the violent pressure effectsof the ejection charge.The diameter and length of the combined payload and hollow nose cone sections placeconstraints on the physical design.

At the time,each of the engineering technology programs (civil, electrical, and mechanical) had their ownfreshman course of two credits and didn’t really want to change. This change would add anadditional two credits to the curriculum which, under university guidelines, would mean that twocredits would have to be dropped elsewhere in the curriculum.

In thisapplication, an AISI 1040 steel with 90,000 psi in tensile strength was selected. AssumingFs =1.5, the allowable working bending stress σ b is found as 60,000 psi.
