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...

They use a low pass filter, followed by a high pass filter. The output of the high pass filter looks great. But (depending on starting conditions) the output of the low pass filter will continuously increase or decrease. Given enough time, your numbers will eventually get to a size that ...

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...
