In (1) the signal is applied between the base and emitter and the
output taken from the collector.
In (2) the signal is applied between the emitter and base and the
output taken from the collector.
In (3) the signal is applied between base and emitter and the output
taken from the emitter.
In order to understand how the transistor works, it is necessary to
consider the properties of all three, and in particular to calculate the
static (d.c.) values and the dynamic (a.c.) values of the various
parameters associated with the three methods of connection.
All circuits considered in this chapter use n-p-n transistors, p-n- ...
