butter函数是求Butterworth数字滤波器的系数,在求出系数后对信号进行滤波时用filter函数。 设计滤波器就是设计滤波器系数[B,A]。 [B,A] = BUTTER(N,Wn,'high') ---用来设计高通滤波器 [B,A] = BUTTER(N,Wn,'low') designs a lowpass filter.--低通滤波器 [B,A] = BUTTER(N,Wn)--带通滤波器 N...

I want to use a low pass Butterworth filter on my data but on applying the filter I don't get the intended signal. Here is the dummy code: Signal A: import numpy as np import matplotlib.pyplot as plt from scipy import signal a = np.linspace(0,1,1000) signala = np.sin(2*np.pi...
In this case, lowpass filter, we can reduce the bandwidth to get a better looking filter. The python/scipy.signal resample function can be used to reduce the bandwidth. Note the resample function will perform filtering to prevent aliasing. Prefiltering can also be perfomed (to reduce aliasing...
