The character theory of compact commutative hypergroups is yet far from being well understood; as this paper shows, the behaviour of the Plancherel measure is related to some deeper harmonic analysis involving notably Sidon sets. Pioneering work related to this area has been performed a long time ago by R. Vrem, K. Ross, J. Fournier (see references below). This elementary study provides only a sample of easy results, but paves the way to apparently much deeper questions.

This paper is comprised of two parts: the first one has been already mentioned; the second provides some easy multiplier theorems. In the context of hypergroups, and despite its elementary character, much of the material presented here is new.
