Abstract
A sur-homomorphism D from n-stage de Bruijn-Good graph to (n-1)-stage de Bruijn-Good graph over ring F2+uF2 was defined. It was proved an algorithm for generating n-stage de Bruijn sequences from a given feedback function of (n-1)-stage de Bruijn sequences. Furthermore,an efficient algorithm for generating n-stage de Bruijn sequences from a given feedback function of lower m-stage de Bruijn sequences by raising stage was given.
