State the functions of radio receiver.

Functions of a Radio Receiver:

1. Signal Reception:
- Receives radio waves from broadcasting stations or other sources.
- Converts the radio waves into electrical signals.

2. Amplification:
- Amplifies the weak electrical signals received to make them stronger.
- This allows them to be processed and heard through headphones or speakers.

3. Demodulation:
- Extracting the original audio or data signal from the modulated radio waves.
- Removes the carrier wave and recovers the desired content.

4. Frequency Selection:
- Allows the user to select the desired radio frequency.
- Tunes the receiver to the specific broadcasting station or frequency.

5. Audio Output:
- Drives the connected headphones or speakers.
- Outputs the demodulated audio signal, converting it into sound.

6. Control:
- Provides controls for volume, tuning, station selection, and other settings.
- Allows the user to adjust the receiver to their desired preferences.

7. Power Management:
- Regulates the power supply to the receiver's components.
- Provides protection against overvoltage or other electrical hazards.

8. Antenna Connection:
- Connects to an antenna that receives and transmits radio signals.
- Improves signal reception and antenna coupling.

9. Display (Optional):
- Some receivers feature a display that shows information such as station name, frequency, or other details.
- Provides user feedback and simplifies operation.
