Abstract

PURPOSE:Two out of eight values are selected so that by using one value, the value of the positive phase component of a variable tap gain will be corrected and by the other, the value of the orthogonal component will be corrected, and the automatization is achieved by two times of multiplication, therby reducing the processing time.
