Motivated by multiplication algorithms based on redundant number representations, we study representations of an integer n as a sum n=@?"k@e"kU"k, where the digits @e"k are taken from a finite alphabet @S and (U"k)"k is a linear recurrent sequence of Pisot type with U"0=1. The most prominent example of a base sequence (U"k)"k is the sequence of Fibonacci numbers. We prove that the representations of minimal weight @?"k|@e"k| are recognised by a finite automaton and obtain an asymptotic formula for the average number of representations of minimal weight. Furthermore, we relate the maximal number of representations of a given integer to the joint spectral radius of a certain set of matrices.
