The term dyadic derivative was coined by F. Pichler for a differential operator introduced by J.E. Gibbs in 1967 which was initially called the logic derivative since being acting on the set of binary n-tuples. Both names, the logic derivative and the dyadic derivative, are related with the property that this set equipped with the addition modulo 2 (EXOR) expresses the structure of a group C_2~n called the finite dyadic group, which is viewed as a natural domain to define binary-valued switching functions.
