一、低通滤波器有源滤波器实质上是一种线性系统,它的动态特性可用n阶微分方程来描述,并能归结为:??对式(1)作拉氏变换,可求得传递函数式:??
First, the low-pass filter Active filter is essentially a linear system, its dynamic characteristics can be described using n-order differential equations, and can be summed up as follows: ?? (1) for the Laplace transform can be obtained Transfer function: ??
