The phase splitter has
one input and two
outputs.
The two outputs are
inverted with respect to
each other. That is, as
one increases in a
positive direction the
other increases in a
negative direction.
In the first diagram the
phase splitting is done
by the transformer.
In the second diagram,
the output from the
collector is an inverted
version of the input.
The output from the
emitter follows the
input.
There is no
amplification from this
circuit because the
emitter is undecoupled.
The word PHASE indicates
a shift in time. In
actual fact there is no
phase change here, only
inversion of the signal.
