Uniqueness of circuits and systems containing one nonlinearity
The nonlinear circuits nonlinear nonlinear elements
2015/8/13
We study systems containing one memoryless nonlinearity. We show that two such systems have the same I/O operator only when they are related by simple scaling, delay, and loop transformations. The the...
