| Abstract: | Serving as the question for study with identification of the frequency response function of the linear system,the effects of noises for estimated accuracy are discussed.The estimating formulae of the frequency response function under the various conditions are difined.The formulae can supply the foundations for theory and can be applied in practical engineering problems. |

| Keywords: | linear system system identification correlation function power spectrum density noise |
