Abstract

Abstract A signal digitization system and method is disclosed which identifies a plurality of sets of spaced intervals of information; defines a strobing window within each spaced interval in one of the sets at a time; strobes the signal during the strobing window; integrates and holds the strobed signal; and digitizes the integrated signal.
