The generalized Rudin-Shapiro function psi is introduced to study the
generalized Rudin-Shapiro sequence, where psi is a continuous (non-dif
ferentiable) periodic function of period 1, oscillating between root q
and (1+root 2)root q. The fractal properties of psi are discussed and
the Box dimension and the Packing dimension of the graph of psi are d
etermined.
