摘要：Audio amplifier is a circuit which is used to generate the audio frequency.Audio amplifier circuits used in radio, television, sound system, and others.Audio amplifier is a low frequency amplifier. Low frequency is meant here isthe vibration in the range 20 Hz to 20 kHz. Each low frequency amplifier can besplit into three parts, namely: 1. Pre Amplifier. 2. Voltage amplifier or driver. 3.Current amplifier (power), or power amplifiers. The essence of all forms ofamplifier circuit of the lowest class to highest class, has the same basic circuitconstruction, and the amplifier circuit itself is really just a refinement of themodulation circuit LF (Low Frequency).
