Comparative analysis of discriminators efficiency of tracking meters under influence of non-Gaussian broadband and band-limited noise

The comparative analysis of the efficiency of processing of signals information parameters by the discriminators of tracking meters when exposed non-Gaussian broadband and band-limited noise is carried out. It is shown that when band-limited noise influences the discriminator, the efficiency of non-linear processing is higher and it the band-limited path and it increases with the increase of the signal/noise ratio. It is shown that the increase of mismatch errors leads to the increase of the length of the linear section of the discriminatory characteristics. The expression is obtained which allows us to determine the characteristics of the nonlinear transformation unit of the discriminator at the current step of nonlinear transformation. Also the expressions and characteristics of the discriminator are obtained for practically important cases.
