利用对偶原则，将带阻型ＲＣ双Ｔ桥滤波器变换成带通型ＲＣ双Ｔ桥滤波器，其等效电路的部分支路呈现负阻抗特性．利用这种特性实现了无源电流放大．最后给出了两个应用电路
By using the duality principle, the RC double T-bridge filter with band-stop is transformed into a band-pass RC double T-bridge filter, and some of its equivalent circuits exhibit negative impedance characteristics. Use this feature to achieve a passive current amplification. Finally, two application circuits are given
