As a final example, we will create a bathtub curve by creating and layering several distributions. 3-1. The Weibull distribution is a 3-parameter distribution. Both Bathtub Curve profiles the failure rate of a large sample of components (or a large sample of systems) as they age. Learn the 6 step process for performing MTBF analysis using Reliability Prediction analysis based on accepted standards. The correct answer is True. 45UI pp for the target BER of 10-9 while no Monte-Carlo BER results are From the analysis, the critical values for the bathtub curve variables equate to a height of 1. The bathtub curve shows the influence of RJ over time It looks a lot like the infant mortality and normal life portions of the bathtub curve in Figure 1, but this curve models only infant mortality (decreasing The three sections of the bathtub curve – early fail, useful life, and wear-out – often have different shapes for failure distributions, as illustrated in the figure. BER bathtub plot: In this example, the white dotted curve is the BER curve measured from the acquired waveform and the orange trace is a bathtub curve calculated from the jitter Figure 5 The bathtub curve is constructed by rescaling the total jitter curve in Figure 4 to one unit interval, and centering the right side of the total jitter curve at 0 UI and the left side at 1UI (the BER Bathtub Curve Plotting BER as a function of the timing offset • Statistical BER estimates the timing margin of ~0.
