| 摘 要： | 本文提出了一种基于输入信号频率的高频补偿动态带宽有源滤波器,它具有随着输入信号频率的改变而改变其高频补偿范围,获得与输入信号的高频变化成正比的动态带宽以及仅有一个RC时间常数和在通频带内具有较高的Q值的特点。实验证明,它具有良好的动态幅频特性和相频特性。

| Abstract: | In this article a kind of high-frequency compensation dynamic bandwidth active filter based on the frequency of input signal is presented. This filter can change its high frequency compensation range with the change of the frequency of input signal. It can obtain dynamic bandwidth in direct proportion to the change of the input signal high frequency. It has only one RC time constant and high Q value in its bandwidth. It has been proved by experiments to have good dynamic amplitude-frequency property and phase-frequency property. |
