            Abstract : 
Exploiting the recent framework of normal factor graphs, this paper presents a transparent exposition of the Krawtchouk transform and its relationship to the Fourier transform and the MacWilliams identities. Such treatment of the subject is believed to be more accessible to wider audience of coding theory.
