The following is a general block diagram of a radio receiver:
Notes:
- Aerial – picks up radio signals from many stations.
- Tuner – selects the signal from just one radio station.
- Detector – extracts the audio signal carried by the radio signal.
- Audio Amplifier – increases the strength (power) of the audio signal. This could be broken down into the blocks like the Audio Amplifier System shown above.
- Loudspeaker – a transducer which converts the audio signal to sound.
The power supply (not shown) is connected to the audio amplifier block.
