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HP...

A high-pass filter is a type of EQ that reduces low-frequency content in your signal by only allowing frequencies above a cutoff frequency to pass through. It’s called a high-pass filter because it lets the high end pass through unchanged while cutting the bass. The term is often abbrevi...
根据高通滤波的算法,我们可以对市场走势进行Highpass Filter。在广发金融工程此前发明的LLT算法就属于高通滤波算法的其中一种。 如果想要在通达信中使用该函数,就要利用C#语言创建通达信dll,以下是通达信高通滤波算法的源代码: namespace NinjaTrader.NinjaScript.Indicators.AUN_Indi.Ehlers ...
Low Pass Filter Response Therefore, in this state, the signal cannot flow through the lane of the capacitor. So the total low-frequency signal will be supplied to the output terminal. High Pass Filter Thecircuit diagram of the high pass filteris shown below. An HPF blocks the low-frequency...
