The transformation of a noisy classical optical signal in a nonlinear-optical converter is discussed with pump depletion taken into account. By means of the Hamiltonian formalism, the possibility of noise transfer between the interacting waves without a change in the total noise in the system is demonstrated. The conditions for noise reduction in both quadratures of the optical signal are found.
