A Simplified Method for Obtaining Requirements of Wiener´s Optimum System

This paper presents a simplified method of deriving Wiener\´s optimum frequency-response system based on the meansquare-error. The initial step follows closely other authors but the final solution is obtained without resorting to cumbersome algebraic manipulation of "completing the square." Furthermore, the present approach is more rigorous and provides a solution representing a unique minimum for the variables considered.
