A probabilistic model of bubble column was derived from a deterministic model so that noncorrelated or autocorrelated noise was added at the column outlet. A pseudo-random binary series of maximum length - PRBS was used as input signal The effect of noise was observed in terms of impulse characteristics calculated by the correlation method from the responses of model to the PRBS input. The possibilities of PRBS when simulating the behaviour of bubble column were judged in the work, and the effect of magnitude of noise amplitude on the form of impulse characteristics was evaluated.
