filtered_signal = hpf(signal, cutoff_frequency) 2.代码解读 上述代码首先定义了一个名为`hpf`的函数,该函数接收一个信号及其截止频率作为输入参数。接着,通过计算nyquist频率和滤波器阶数,调用Butterworth函数生成高通滤波器的系数。最后,使用`filtfilt`函数对原始信号进行滤波处理,得到滤波后的信号。 四、应用场景与...

Learn how to use and design high-pass filters. Resources include videos, examples, and documentation covering digital filters and other topics.
You use a pass filter’s cut-off frequency as a reference for the point at which frequencies to one side are filtered and to the other side are allowed to pass. It is worth noting that the cut-off frequency is not the point at which attenuation begins. It is actually the point at wh...

In auditory perception, a right hemisphere (RH)/left ear advantage(LEA) for low-pass filtered stimuli and a left hemisphere (LH)/right ear advantage(REA) for high-pass filtered stimuli have been reported. Here we investigated how tonal language experience modulates this hemispheric asymmetry. We...
In a vehicle suspension control in which the output of a vehicle body mounted absolute vertical acceleration sensor is integrated to provide an absolute vertical velocity signal, the sensor output is high pass filtered to remove DC components but pass components in the frequency range 1-2 Hz. The...
