An Analysis of the Electromyogram by Fourier, Simulation and Experimental Techniques

摘要: The electromyogram of a single motor unit is studied by considering it as time function defined convolution integral where point process input passes through filter whose impulse response the shape action potential. interspike intervals are assumed to be normally distributed, independent random variables. Simulation performed on digital computer. theoretical analysis shows that absolute value ensemble average Fourier transform simulated EMG approaches This has been confirmed simulation except at very low end spectrum. These results compared with transforms recorded surface data from human muscles.
