Abstract

PURPOSE:As for the equalization in a frequency range, the phases of equivalent wave forms are changed freely and as for the equalization in a time range, the phases of the carriers of respective branch circuits are changed freely, so that even the simple circuit constitution having only one equializer sequence will made possible to perform the excellently-precise-equalization.
