Abstract:	本專題提出一種用於由Antoniou電路模擬電感實現二階濾波器的有效方法，是採用MATLAB模擬與頻譜分析儀測量二階四種型式濾波器〈低通、高通、帶通和帶拒〉的轉移曲線，並分析比較。有趣的是，由OP741組成的Antoniou電路在二階LP、BP、RN和LPN中，其振幅響應因無法容忍非理想OP的特性，而難以捉摸。這就是使用Antoniou電路時需注意的部份。本專題針對這點提出一個有用的經驗，也針對這點來改善Antoniou模擬電感電路。 This paper presents an efficient method for the second-order filters with a simulated inductance realized by the Antoniou circuit. The transfer curves of the second-order filters, inclusive of low pass, high pass, band pass, and notch types, are simulated by MATLAB and measured by the spectrum analyzer, and they are analyzable and comparable. Interestingly, because the Antoniou circuit composed of 741s, resistors, and capacitors are intolerant of the non-ideal properties of op amps, the LP, BP, RN, and LPN responses are intangible. It is a key factor. This paper is mainly aimed at this to propose a useful experience and manage to improve it.
