Abstract :
A frequency domain stability criterion for nonlinear time-varying (NLTV) discrete systems with a separable time-varying nonlinearity is derived using the Lyapunov approach. It is shown that Szegö´s [1] criterion for nonlinear time-invariant discrete systems and Chen´s [4] criterion for linear time-varying discrete systems can be obtained as special cases of the criterion derived here.
