随着电子科学技术的迅速发展，滤波器系统也要求有新的设计思想和观点，使系统能在可行的条件下得以实现，而且其功能也达到更高的指标．为此，用集成电路来进行设计是一种有效而理想的办法．现介绍一种六阶有源低通滤波器的设计方法．此设计有一定实用价值，且设计出来的滤波器电路具有成本低、重量轻、可靠性好、元件数目少、简单、调整方便等优点．
With the rapid development of electronic science and technology, the filter system also requires new design ideas and perspectives so that the system can be realized under feasible conditions, and its function reaches a higher target. For this reason, using integrated circuits to design is an effective and ideal way. Now introduced a sixth-order active low-pass filter design. The design has certain practical value, and the designed filter circuit has the advantages of low cost, light weight, good reliability, fewer components, simple and convenient adjustment.
