本文提出了用单个运算放大器构成三阶低通滤波器的设计方法,给出了用BASIC语言写成的计算此类滤波器中各参数的程序.文末列举了一则设计实例,并简介将该例中的滤波器用于某控温仪表模入通道中的效果.
This paper presents a single op-amp third-order low-pass filter design method is given in BASIC language is written to calculate the parameters of such a filter program. At the end of the article cited a design example, and an introduction to the case In the filter for a temperature control instrument into the channel effect.
