Signal processing methods based on the combined use of the continuous wavelet transform (CWT) and zero-crossing technique were applied to the simultaneous

A two dimensional dual-tree complex wavelet transform is performed in the spectral derivative domain, where the noise level is elevated temporarily to avoid

For the spectral analysis of the EMG signal of the studied muscles, mean values of median frequency (MF) were used, obtained using the short-term fast Fourier transform (ST-FFT)
