Simple Audio Amplifier Block Diagram. You only need a few capacitors to make a decent stereo amplifier out of it. Aerial picks up radio signals from many stations.
This could be broken down into the blocks like the audio amplifier system. Aerial picks up radio signals from many stations. As you can see from the main image we have made the circuit on a piece of perfboard.
But recently i found this awesome little chip called tea2025.
Tuner selects the signal from just one radio station. This block diagram of an audio system shows all the stages from microphone to speaker and follows the design of a typical pa system. Detector extracts the audio signal carried by the radio signal. The amplifier circuit diagram shows a 2 5w 2 stereo amplifier.
