An official IEEE document at any point in time consists of the current edition of thedocument together with any amendments, corrigenda, or errata then in effect. Every IEEE standard is subjected

25、 to review at least every ten years. When a document is more than ten yearsold and has not undergone a revision process, it is reasonable to conclude that its contents, although still ofsome value, do not wholly reflect the present state of the art. Users are cautioned to check to determine thatthey

26、 have the latest edition of any IEEE standard.In order to determine whether a given document is the current edition and whether it has been amendedthrough the issuance of amendments, corrigenda, or errata, visit the IEEE-SA Website at http:/ieeexplore.ieee.org/ or contact IEEE at the address listed

By publication of this standard, no position is taken by the IEEE with respect to theexiste

29、nce or validity of any patent rights in connection therewith. If a patent holder or patent applicant hasfiled a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE-SA Website at http:/standards.ieee.org/about/sasb/patcom/patents.html. Letters of Assur
