vsub
Vsub is not a standalone concept with a single fixed definition; rather, it refers to the use of a subscripted voltage variable in scientific and engineering notation. In many contexts, V_sub denotes a voltage quantity labeled with a subscript to distinguish it from other voltages in a circuit, system, or model. This convention helps users track multiple voltages such as V_subin, V_subout, V_subref, or V_sub1 within the same schematic or analysis.
In electronic circuit analysis, subscripted voltages commonly indicate the potential at specific nodes or across particular
The term Vsub itself is typically encountered in plain-text documents, manuals, or informal discussions where subscripts
