摘要
由于惰性电路组件如LC谐振回路、压电陶瓷、石英晶体等都具有储能的作用,通常其能量不能突变,因此要经历过渡过程。本文采用拉普拉斯变换分析了相移键控调制PSK信号激励下滤波器的暂态响应,并用Matlab软件进行了数字仿真,揭示了影响暂态过程峰值的因素,对特殊通信滤波器的设计和教学有一定意义。
The inert components has the action of storing energy, such as LC resonance loop, piezoelectric ceramic and quartz crystal. Its energy can not be mutation and must go through the transition process. Using the Laplace transformation, this paper analyses the transient response of filters when inspired with phase shift keying modulated signals, and simulates it based on Matlab, and reveals the impact factors on the peak of transient process. It will be beneficial to special filter design and teaching in communications.
