In this paper mean square error (N - is order of trigonometric polynomial) of a trigonometric interpolation of a periodic signal is calculated. The results are obtained for the case when interpolation time interval contains non-integer number of the signal periods. It is proved that contrary to popular opinion error tend to some value depending on Analytical expressions for the lower bound estimation of are obtained.
