Nonlinear pulse system and ''equivalent'' system is obtained due
to the exchange pulse element by static characteristic are
considered. Critical case of the one zero root characteristic
equation of the linearized system is researched.
Stability by the first approximation of equivalent system implies
asymptotic stability of nonlinear pulse system is obtained.
