研究了利用最优逆滤波器从非侵入式结构振动测量数据重建内燃机压力迹线的可行性。这个问题被正式措辞到本文第一部分介绍的循环平稳过程的一般框架。证明了最优逆滤波器是周期变化的。为了有效地应用所提出的去卷积方案，给出了许多指导方针。
This part addresses the feasibility of reconstructing the pressure trace in IC engine from non-intrusive structural vibration measurements by means of an optimal inverse filter. The problem is formally phrased into the general framework of cyclostationary processes introduced in Part I of this paper. It is proved that the optimal inverse filter is periodically varying. A number of guidelines are given for efficiently applying the proposed deconvolution scheme.
