We present a novel method for studying the formation of a disoriented chiral condensate (DCC) in high energy heavy-ion collisions utilizing a discrete wavelet transformation. Because of its salient feature of space-scale locality, the discrete wavelet proves to be very effective in probing physics simultaneously at different locations in phase space and at different scales. We show that the probability distributions of the neutral pion fraction for various rapidity-bin sizes have distinctive shapes in the case of a DCC and exhibit a delay in approaching the Gaussian distribution required by the central limit theorem. We find the wavelet power spectrum for a DCC to exhibit a strong dependence on the scale while an equilibrium system and the standard dynamical models such as HIJING have a flat spectrum. {copyright} {ital 1996 The American Physical Society.}
