We discuss the production of induced noise by a pulse and the propagation of the noise in moen rothbury faucet a dispersive medium.We present a simple model where the noise is the sum of pulses and where the mean of each pulse is random.We obtain explicit expressions for the standard deviation of the spatial noise as a function of time.We abc material also formulate the problem in terms of a time-frequency phase space approach and in particular we use the Wigner distribution to define the spatial/spatial-frequency distribution.
