A-29. A device that provides two output signals that differ in phase from a single input signal.
A-30. A phase splitter is used to provide the input signals to a push-pull amplifier.
A-31. A push-pull amplifier is used when high power output and good fidelity are needed.
A-32. A push-pull amplifier provides more gain than a single transistor amplifier.
