A mathematical description of voltage fluctuations at the output of a linear system at the input of which there are random perturbations produced at random moments of time. If is the output of the system at time resulting from a single pulse applied at time , the shot effect may be described by a stochastic process

where are the arrival moments of pulses, while are random variables characterizing the magnitudes of the intensities of the pulses. In the particular case when , , , the are independent, uniformly-distributed random variables with finite variance, while forms a Poisson flow of events with parameter , the process is a stationary stochastic process in the narrow sense, with
