It is considered a possibility of application of a method of decomposition of an autocorrelated matrix of a signal on own numbers in virtual measuring devices for signals parameters measurement in the conditions of action noise and hindrances. Which is based on the analysis of own values of an autocorrelated matrix of a signal, thus there is a division of information into two vector subspaces – a signal and noise and subsequently processed the signal subspace. It is provided the short description of this method. Technique creation, basis on the modeling of the method, providing the necessary accuracy of measurement is offered at preset values of parameters of a signal registration. The review is given to influence of various factors on determination of parameters of a harmonious signal in the conditions of action noise and hindrances on the basis of this method. Dependences the result of modeling are given method. Measurement errors amplitude and frequency of a signal are estimated and formulated some recommendations about their reduction.
