一、概述高通型加载系统的一个突出特征是,出现传递函数分子的阶次高于或等于分母阶次的情况。在实验过程中输出信号的相移不但不落后,反而超前输入信号,而且随着输入信号频率增大,超前相移也增大。这与一般随动系统的输出输入关系是完全相反的。 First, an overview of high-pass type loading system is a prominent feature of the transfer function appears higher order or higher than the order of the denominator. During the experiment, the phase shift of the output signal not only does not lag behind, but leads the input signal ahead of time, and as the input signal frequency increases, the leading phase shift also increases. This is the output of the general input system with the input relationship is completely opposite.
