# [scipy.signal](https://docs.scipy.org/doc/scipy/reference/signal.html) -- Butterworth low, high and band-pass
|
||
|
|
## Goal
|
||
|
|
|
||
|
|
Sometimes we need to remove of frequency range from a time series. For this we can use a Butterworth filter [scipy.signal.butter](https://docs.scipy.org/doc/scipy/reference/generated/scipy.signal.butter.html) and the [scipy.signal.filtfilt](https://docs.scipy.org/doc/scipy/reference/generated/scipy.signal.filtfilt.html) command.
