The nonlinearity in discrete nonlinear systems of the block-oriented f
orm is estimated. In particular, memoryless, cascade and parallel mode
ls are examined. Algorithms being in the form of the ratio of two Lagu
erre polynomials are proposed, and their asymptotic properties are est
ablished. The conditions for the pointwise and global consistency are
found. The identification algorithms are consistent for a large class
of nonlinear characteristics which cannot be parametrized.
