In this paper we analyse and quantify the damage to the quality of spectrum estimation of discrete-time signals when a finite number of the signal samples are lost. We assume that the positions of the lost samples, of otherwise uniformly sampled signal, are random. We modify a DTFT-based spectral estimator to remove bias from the spectral analysis. Then we derive the standard deviation of the estimator and use it as the measure of accuracy. Simulation results confirm validity of the results presented in this paper.
