A new initialization scheme for the Remez exchange algorithm is proposed. More specifically, the solution of the well known "don't care" filter design method is proposed as a new efficient initialization scheme for the Remez algorithm. Our proposal is motivated by the fact that the "don't care" least squares optimum solution satisfies one of the two basic conditions that are sufficient for obtaining the L/sub /spl infin// optimal solution according to the alternation theorem and at the same time it adequately approximates the second one. Because of these properties we have a significant speed up of the convergence of the Remez exchange algorithm to the L/sub /spl infin// optimum solution.
