Weball of whose roots are complex. When we apply Graeffe's method to an equation whose roots are complex, we get directly not the roots themselves but their absolute values. To determine the roots we must have recourse to the original equation and to the explicit expressions of the elementary symmetric functions of the roots of the equation. WebFeb 16, 2006 · To calculate the root-mean, one may simply apply Newton's Method for calculating the square root to the mean value. As long as the averaging time is long compared to the sample period (t &62;&62; 1/f S), one iteration of the square root calculation should suffice for reasonable accuracy. This seems simple enough, but we …
