This work investigates the viability of myoelectric signal recognition by processing and analyzing the power spectral density of this signal. As shown in this text, the proper recognition of four distinct myoelectric signal classes was achieved using this methodology, being each of these classes ...

with the Hilbert transform. High-gamma power was calculated by averaging the analytic amplitude across these eight bands. The signal was subsequently downsampled to 100 Hz. The signal wasz-scored based on the mean and standard deviation of a baseline period (from −50 to 0 ms before th...
Con- tinuous multitaper time–frequency spectral analyses were conducted for data from 2 s before to 4 s after onset of the tone. LFP signals were normalized to those recorded 2 s before the onset of the tone. The ratio of theta (4–8 Hz) power after the onset of the tone vs ...
