Nonlinear filtration of quasi-gaussian signals

Abstract

The definition of quasi-Gaussian signals as one class of semicontinuous processes is given. On the basis of a nonlinear optimization problem and the method of variation calculus, the transient response of a nonlinear filter-discriminator is determined, which performs the functions of selective filtering and evaluating the signal value. The advantages of the obtained result in terms of the mean square error in comparison with the known filtering methods are shown
