The most common technique used for modeling linear, time-invariant systems is the block diagram, with the mathematical model represented as a transfer function. As an example of the first situation - ...

The synchronous machine can be represented by a simple and easily surveyed block diagram from which can be derived all possible transfer functions. Because of the introduction of complex ...

Abstract: This paper presents a new concept called harmonic domain dynamic transfer function (HDDTF), which characterizes the dynamics of a nonlinear, time-periodic network as seen from a port (or ...

A nice derivation of Z-Transform from the block diagram by Waleed Al-Nuaimy is very clear to follow. Z-transform (developed/rediscovered in the late 1940s) converts a discrete-time signal, which ...
