Superposition principle in linear networks with controlled sources
The manuscript discusses a well-known issue that, despite its fundamental
role in basic electric circuit theory, seems to be tackled without the needful
attention. The question if the Principle of Superposition (POS) can be applied
to linear networks containing linear dependent sources still appears as an
addressed point unworthy to be further discussed. Conversely, the analysis of
this point has been recently re-proposed [5,6] and an alternative conclusion
has been drawn. From this result, the manuscript provides an alternative
approach to such issue from a more general point of view. It is oriented to
clarify the issue from the didactic viewpoint, rather than provide a more
efficient general technique for circuit analysis. By starting from a linear
system of equations, representing a general linear circuit containing
controlled sources, the correct interpretation of turning off the controlled
elements in terms of circuit equivalent is provided, so allowing a statement of
the POS for linear circuits in a wider context. Further, this approach is
sufficiently intuitive and straightforward to fit the needs of a Basic Electric
Circuit Theory class
