Abstract
A general expression for the power spectrum of a sequence of pulses having time intervals distributed according to an arbitrary probability function and presenting a correlation between pulse shape and pulse intervals is given. Such a correlation is described by means of another arbitrary distribution function giving the joint probability of the parameters that characterize the shape of each pulse in terms of the time interval between that pulse and the preceding one. The expression that has been found is suitable for direct numerical computation and could be applied to many processes of physical interest, some of which are described in the paper.
