建议使用一个差分输入运算放大器的有源网络，适合实现高Q因数二阶带通功能。发现其对元件值的 Q 灵敏度小于 Huelsman 和 Antoniou 相应网络的最佳 Q 灵敏度。该网络已用于实现三级联的六阶带通滤波器。给出了实验结果。
An active network is suggested that uses one differential-input operational amplifier and is suitable for realising high-Q factor second-order bandpass functions. Its Q sensitivity to component values is found to be less than the optimum Q sensitivities of the corresponding networks of Huelsman and Antoniou. The network has been used to realise a sixth-order bandpass filter in three cascaded stages. Experimental results are given.
