Abstract

In conventional successive projection (SP) method, only one extreme frequency point at which the deviation from the given specification is maximized is used in the update of the filter coefficients. Therefore, enormous amount of iteration numbers are necessary for research the solution which satisfies the given specification. In this paper, we propose a design method of filters with the restricted roots by SP method using multiple extreme frequency points based on Fritz John's theorem. As a result, the solution converges less iteration number than the conventional SP method.
