Successive Projection Method, Fritz John's Theorem, Multiple Extreme Frequency Points, fir filter design
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 iter ation numbers are necessary for research the solution which satisfies the given specification. In this paper, we propose a design method of filters by SP method using multiple ex treme frequency points based on Fritz John's theorem. As a result, the solution converges less iteration number than the conventional SP method.
