摘要
本文利用计算机研究了Q值对二阶低通有源滤波器的幅频特性的影响。程序是用QBASIC语言编制的。同时给出了分析和打印结果,该方法可以被推广到对其它滤波器的研究。
The effects of Q values on the amplitude-frequency characterstic of an active filter have been studied by using computer.The program is in QBASIC language and provides print results and graphes.This method may he applied to other filters.
