Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H13K 500

US Classification:

327553

Abstract:

A method and system for providing a filter having an increased speed and decreased settling time are disclosed. The method and system comprise summing means for adding and subtracting. The method and system further comprise means coupled to the summer for providing a delay; and a clock coupled to the delay providing means. The clock determines a number of samples during a predetermined time. The clock is operated at a plurality of frequencies such that the total number of samples during the predetermined time is a predetermined number.
