In order to define the rates and orders of R-convergence, one uses the rate and order of Q-convergence of am error-bounding sequence () chosen such that no other error-bounding sequence (′) could have been chosen that would converge with a faster rate and order; any (′) provides a lower bound on the rate and order of R-convergence and the ...

One definition of signal-to-noise ratio is the ratio of the power of a signal (meaningful input) to the power of background noise (meaningless or unwanted input): =, where P is average power.

Any non-linear differentiable function, (,), of two variables, and , can be expanded as + +. If we take the variance on both sides and use the formula [11] for the variance of a linear combination of variables (+) = + + (,), then we obtain | | + | | +, where is the standard deviation of the function , is the standard deviation of , is the standard deviation of and = is the ...
