摘要
负载变化键控 (Load- Shift- Keying)也被称为反射调制 [1 ]。LSK运用于耦合线圈中次级线圈阻抗的变化能经耦合反射至主线回路并对主线圈回路产生影响这一性质 ,从而通过调制负载阻抗来实现信号的传递。线圈的耦合系数 k是表征线圈间耦合程度的参量。本文在介绍负载变化键控制原理的同时 ,提出了对实际回路中线圈耦合系数
Load Shift Keying (LSK),which was referred as 'reflectance modulation',is a particular form of ASK.LSK utilized the property of an inductive couple in which a change of the secondary load is reflected onto the primary coil as a varying impedance.K is the coupling coefficient defined by geometrical parameters.
