1、利用锁相环路实现解调。有关这种解调方法的内容将在 2、利用调频波的过零信息实现解调。因为调频波的频率是随调制信号变化的,所以它们在相同的时间间隔内过零点的数目将不同。当瞬时频率高时,过零点的数目就多,瞬时频率低时,过零点的数目就少。(讲义下册P59图6.2.15)利用调频波的这个特点,可以实现解调。例如BE1调制度测量仪

Chapter 3 Fundamentals of Inviscid, incompressible Flow Theoretical fluid dynamics, being a difficult subject, is for convenience, commonly divided into two branches, one treating frictionless or perfect fluids, the other treating of viscous or imperfect fluids. The frictionles fluid has no existence in nature, but is hypothesized by mathematicians in order to facilitate the investigation of important laws and principles that may be approximately true of viscous or natural fluids

This chapter mainly deal with the properties of two-dimensional airfoils at mach number above 0.3 but below 1, where the compressibil ity must be considered
