“Understanding Modern Electronics” S:1 E:9 Building an Audio Amplifier

S:1 E:9 Building an Audio Amplifier Put your knowledge to use by building a complete audio amplifier. First, create a two-stage amplifier, then add capacitors to increase the amplification, or gain. Add a power output stage to drive a loudspeaker. Finally, add a volume control. In addition, learn how biasing with diodes can eliminate a subtle form of distortion.
