The concept of iterated bilateral Laplace transform (ILT) is used to obtain the frequency response of linear time-varying (LTV) causal circuits and systems. It is shown that the application of this commonly overlooked transform is essential in the an

In this article we elaborate on various characterisations of nonlinear systems. Specifically, we focus on the frequency-domain characterisation of the class of single-input single-output SISO linear time-varying LTV systems. We use the model introduc
