We consider the construction of linearly parametric discrete model in form of stochastic difference equation which describes the sequence of measurements of amplitude-frequency characteristic of dissipative system with linearly viscous friction. The numerical iterative method of mean-quadratic estimation of coefficients of stochastic difference equation is suggested. The comparative analysis of introduced algorithm of calculation of system dissipative characteristic with known method of resonance curve is made.
