Operating as a normal transistor, the Emitter leg outputs a signal in-phase while the Collector leg outputs a 180 degree out of phase signal.

As with many of these transistor circuits Q1 is a NPN transistor.

Vcc is left up to the user, just keep it in-line with the transistor used.

The capacitors [C1, C2, C3] are all just DC blocking capacitors.

Resistors R1 and R2 form a voltage divider to bias the Base of the transistor.

Note that the outputs are Collector to ground and Emitter to ground.
