所述的有源带通滤波器是采用现代网络理论，通过查图表反复计算数值调试并利用多项式综合滤波器的设计理论得到的设计结果，从频率响应特性曲线和电路结构可见，它完全满足了设计时所提供的各项技术指标的要求。文中详细地讨论了由单元电路到全极点多反馈滤波网络电路设计时的理论根据，各支路参数实际的计算和调试方法。这种电路结构简单合理，调试和维修十分方便，代替了无源滤波器中的大型电感和电容，有利于设备小型化。
The active band-pass filter is based on the modern network theory, through the chart chart repeatedly calculate the value of debugging and design using polynomial synthesis filter design results obtained from the frequency response characteristic curve and the circuit structure can be seen, it fully satisfies the Design specifications provided by the technical indicators. In this paper, the theoretical basis of circuit design from the unit circuit to the all-pole multi-feedback filter network is discussed in detail, and the actual calculation and debugging methods of each branch parameter are discussed. This circuit structure is simple and reasonable, debugging and maintenance is very convenient, instead of a large passive inductor in the inductor and capacitor, is conducive to miniaturization of equipment.
