Uniqueness of a basic nonlinear structure
Nonlinear structure nonlinear linear time-invariant general circuit
2015/8/13
In this paper we show that systems consisting of a memory-less nonlinearity sandwiched between two linear time-invariant (LTI) operators are unique modulo scaling and delays. We mention a few corollar...
