【Abstract】 Treatment of tendency part is the major stage of signal detection technique, in this article,the general model of the tendency part is created by applying the least-square principle. Applying the powerful matrix calculating function of MATLAB, the nonlinear tendency part in the period signal is canceled, and the expected effect is got.更多还原
