WebStep 3: Finally MTBF can be calculated using the above formula. MTBF = TOT / F. Step 4: Failure Rate is just the reciprocal value of MTBF. Thus the formula is, FR = 1 / MTBF. Relevance and Uses of MTBF Formula. MTBF value simply tells about a product’s survival time. It is very important in Hardware product Industries rather than consumers. WebThe metastability occurrences can be predicted by using the mean time between failures (MTBF) formula: Where C1 and C2 are constants that depend on the technology used to build the flip-flop; tMET is the ...
