EmgEnvelopProcessingFilter

class pyCGM2.EMG.emgFilters.EmgEnvelopProcessingFilter(acq: btkAcquisition, labels: List)

Filter for processing EMG envelope from low-pass filter.

This filter processes the rectified EMG signals by applying a low-pass filter to generate the EMG envelope.

Parameters:

• acq (btk.btkAcquisition) – BTK acquisition instance containing EMG data.

• labels (List[str]) – List of EMG channel labels to process.

__init__(acq: btkAcquisition, labels: List)

Initializes the EmgEnvelopProcessingFilter with acquisition data and EMG labels.

Methods

__init__(acq, labels)	Initializes the EmgEnvelopProcessingFilter with acquisition data and EMG labels.
run()	Run the low-pass filter to generate the EMG envelope for each specified channel.
setCutoffFrequency(fc)	Set the cut-off frequency for the low-pass filter.

run()

Run the low-pass filter to generate the EMG envelope for each specified channel.

setCutoffFrequency(fc: float)

Set the cut-off frequency for the low-pass filter.

Parameters:

fc (float) – Cut-off frequency for the low-pass filter.
