- Modulation: The audio signal modulates a radio frequency (RF) carrier wave, varying its frequency based on the input signal.
- Frequency Multiplication: The modulated signal undergoes frequency multiplication to reach the desired transmission frequency.
- Amplification: The amplified signal is then boosted to a sufficient power level for transmission.
- Antenna Emission: The amplified signal is sent to an antenna, converting the electrical signal into radio waves, transmitting the modulated audio signal through the air.
