toto.filters.bandpass_filter

Creates Fourier low, high, or bandpass filter.

Parameters

input_array(Panda Obj)

The Panda dataframe.

lower cut-off (s)float

The minimum period filter cutoff

upper cut-off (s)float

The maximum period filter cutoff

Notes

• lower cut-off set < (2*delt) for no cutoff at high freq end

• upper cut-off set > (length(data)*delt) for no cutoff at low freq end

Examples:

>>> df['bandpass']=bandpass_filter.bandpass_filter(df['signal'].copy(),    args={'lower cut-off (s)':3600*30,'upper cut-off (s)':24*3600*30})
>>> 

toto.filters.bandpass_filter.bandpass_filter(input_array, args={'lower cut-off (s)': 0.0, 'upper cut-off (s)': 0.0})
