The problems of the synthesis and analysis of discriminators under the influence non-Gaussian noise with a band-limited are considered. It is shown that in the above case, the discriminator is dual channel. Therefore the characteristics of the nonlinear transformation unit of the discriminator are deter-mined by the Fisher information relative to the density of probability distribution of the amplitude of the mixture of non-Gaussian band-limited noise and mismatch errors. The ratios are obtained, that allow us to estimate the efficiency of the signal processing with mismatch errors taken into account. It is shown that when processing is non-linear, the power of the band-limited noise at the output of the discriminator is smaller than the power of the broadband noise.
