Second-order highpass difference filterChienPing WuChangDa Tsai
A second-order differential highpass filter constructed according to the present invention includes a difference amplifier and a feedback processing circuit. The difference amplifier includes an operational amplifier OP.sub.1, and four resistors R.sub.3, R.sub.4, R. sub.5 and R. sub.6, ...
Other chapters briefly introduce a design process of simple second order low-pass and high-pass filter. A theory of current conveyors is discussed too, because they are the basic building blocs of proposed synthetic element and also active frequency filters. Finally, the particular solutions of ...
Thefrequency response of second order high pass filteris similar to the first order high pass filter. But in second order high pass filter stop band will be twice that of first order filter at 40dB/Decade. Higher order filters can be formed by cascading first and second order filters. Altho...

而我们处理的方式是使用HPF(High-pass filter):HPF是一种特殊的EQ,如同它的名字:让高于特定频率(cutoff frequency)的讯号通过,换句话说,就是滤掉所有低于特定频率(cutoff frequency)的讯号。 HPF的控制主要就是要决定Cutoff frequency的高低,而我们的目标是:清掉除了Bass、Kick以外听起来不明显但无用的低频。挂上...
