Representation of five potential sEMG preprocessing pipelines composed of different basic building blocks. The most appropriate pipeline to use will depend on the target application scenario and may differ from the ones shown. a Simple pipeline for data checks. b Gating pipeline for strong ECG interference when EMG amplitudes are to be maintained. c Wavelet denoising as the go-to method in most cases (e.g., for raw EMG analyses). d Fixed sample entropy for robust envelope calculation without additional ECG removal. e Illustration of advanced preprocessing pipeline comprising multiple iterations of ECG removal and crosstalk removal
