torch_ecg.utils.butter_bandpass_filter¶
- torch_ecg.utils.butter_bandpass_filter(data: ndarray, lowcut: Real, highcut: Real, fs: Real, order: int, btype: str | None = None, verbose: int = 0) ndarray[source]¶
Butterworth bandpass filtering the signals.
Apply a Butterworth bandpass filter to the signal. For references, see [1] and [2].
- Parameters:
data (numpy.ndarray) – Signal to be filtered.
lowcut (numbers.real) – Low cutoff frequency.
highcut (numbers.real) – High cutoff frequency.
fs (numbers.real) – Frequency of the signal.
order (int) – Order of the filter.
btype ({"lohi", "hilo"}, optional) – (special) type of the filter. Ignored for lowpass and highpass filters (as defined by lowcut and highcut).
verbose (int, default 0) – Verbosity level for printing.
- Returns:
y – The filtered signal.
- Return type:
