NEETS Module 8, Chapter 1

The IDEAL FREQUENCY RESPONSE of an audio amplifier is equal gain from 15 Hz to 20 kHzwith very low gain outside of those limits.A PHASE SPLITTER provides two output signals that are equal in amplitude but different in phasefrom a single input signal. Phase splitters are often used to provide input signals to a push-pull amplifier.NTS0801I-18A PUSH-PULL AMPLIFIER uses two transistors whose output signals are added together toprovide a larger gain (usually a power gain) than a single transistor could provide. Push-pull amplifierscan be operated class A, class AB or class B.1-38
