Our results show that the rate of correlation among the random variables of those output sequences are low although they are not independent; in addition, the output sequences of those combined generators are homogeneous Markov chains which are strictly stationary processes with ergodicity; the output sequences of those combined generators are also proved to summit to the strong law of large numbers and the central limit theorem; finally the computation formula of the rate of the accordance between the output sequences and input sequences of those combined generators is given.

Secondly, the properties of output sequences of stop-and-go clocked combiners are discussed. It is proved that the output sequences are stationary and obey strong law of large numbers and central limit theorem. Using the probabilistic model properly built, we analyze the rate of coincidence between the output sequences of two kinds of generators with basic operations and corresponding LFSRs sequences. All the computational formulae are derived. A recursive algorithm for efficiently computing the poster probability of partial input strings and corresponding joint probability is introduced. Moreover, divide-and-conquer attacks on this kind of generators which reconstruct the initial states of the input stop-and-go generators individually are proposed.

Overall, you, as end-customer will not directly benefit from PFC. In the long-term it will save you money and problems. Less load on the grid means less likeliness of black-outs. Less load on the power company's generators means that their prices will not go up as fast as they would when they needed to buy bigger generators.

整体来说，身为最终使用者不会直接从PFC电路设计受益，长远看来将为你省下金钱以及问题，电力系统上较小的负荷也代表跳电次数也会降低，发电厂发电机组负荷较少，代表电费不会因为他们需要更大的发电机组而提高。
