1. one kind reduces system (10;

  • The method of the tandem quantization

         300), this system comprise a plurality of quantification equipment (30,70 connected in series;

    350,370), the method comprising the steps of;

    (a) analyze this system (10;

         300) signal area (290) of operation to determine that the tandem noise error is taken place;

    And(b) revise this system (10;

         300) one or more in have the back to the more preceding quantification equipment of proofreading and correct (30;

         350), with the tandem noise that reduces to cause from described definite signal area, described one or more more preceding quantification equipment (30;

         350) do not comprise this system (10;

         300) last quantification equipment (70 of serial;

         370).
