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 … WebMar 13, 2015 · Here's an implementation of square root function using Newton-Raphson method. The basic idea is that if y is an overestimate to the square root of a non-negative real number x then x/y will be an underestimate, or vice versa, and so the average of these two numbers may reasonably be expected to provide a better approximation. green street west virginia cross lanes
