| Abstract: | In this paper a method of estimating the coefficients of the AR model and power density spectrum(PDS) of NEMG signal by using a three layer artificial neural network(ANN), in which the transfer function of hidden units is linear, is introduced.Experiment results show that coefficients of the AR model and PDS of NEMG derived from either ANN and auto correlation method are very similar to each other. It indicates that the method introduced in this paper works well. |
