AUDIO AMPLIFIER TRAITS CLASS A CLASS AB CLASS B CLASS C CLASS D AS WELL AS UNDERSTANDING THE FUNCTION OF THE AMPLIFIER
POWER AMPLIFIER UNDERSTANDING: The amplifier is a series of electronic components which are used to strengthen the power (or in General). In the field of audio, amplifiers will strengthen signal sound shaped analogue of sound source i.e. strengthen signal/gain current (I) and voltage (V) Power AC signal from its input shaped into electric current and voltage AC, its also will be larger at the output. FUNCTION: Amplifier or Audio Amplifier is an amplifier that serves to strengthen the audio signal is then fed to the loudspeaker. VARIOUS: ✓ CLASS A: Characteristics: • Output Signals are working on the active region. • Re-imports are high. • The shape of the output signal is exactly the same as the input. • A low Efficiency. • The transistors are always ON so most of the resources wasted into heat power supply • Class A amplifier Transistor needs to be coupled with extra cooling (e.g. larger heatsink) ✓ Class B: characteristics: • Pushpull or transist
