11.1 CONVENTIONAL NOTATIONS
When we indicate a voltage V we need two subscripts that suggest the two nodes
across which the voltage is applied (e.g., V
BE
). We use only one subscript (e.g., V
B
)
to refer to a voltage applied across the node indicated by that subscript and the
(implicit) ground. When only one subscript that is doubled is used (e.g., V
CC
), we
refer to a voltage owing to a DC source, applied across the node indicated by the
subscript and the ground.
Examples: V
CE
indicates the voltage across nodes “C” and “E,” V
B
indicates the
voltage across node “B” and the ground, V
BB
indicates the voltage owi ...
