In this paper a cylindrical multivalued logic transform is defined. The transform is defined in terms of cylindrical multivalued Walsh functions. It is shown that these functions form an orthogonal set. The number of independent constraints needed to define these functions is shown to be equal to (m+1)/2. The cylindrical Walsh functions form a complete set. Thus, the transform can be used to expand the two dimensional functions as a series of multivalued cylindrical functions.
