vital_sqi.preprocess.band_filter module

Filtering of raw signals by bandpass

class vital_sqi.preprocess.band_filter.BandpassFilter(band_type='butter', fs=100)

Bases: object

signal_bypass(cutoff, order, a_pass, rp, rs, btype='high')

signal_highpass_filter(data, cutoff, order=5, a_pass=3, rp=4, rs=40)

High pass filter as described in scipy package :param data: list, array of input signal :param cutoff: :param fs: :param order: :return:

signal_lowpass_filter(data, cutoff, order=3, a_pass=3, rp=4, rs=40)

EXPOSE Low pass filter as described in scipy package :param data: list, array of input signal :param cutoff: :param order: :param a_pass: :param rp: The maximum ripple allowed below unity gain in the passband.

Specified in decibels, as a positive number.

Parameters

rs – The minimum attenuation required in the stop band. Specified in decibels, as a positive number
