  2. WHAT IS RADIO COMMUNICATION? • Radio communication involves the transmission and reception of messages through signals carried by the radio waves. • Radio waves are EM waves used widely in communication. These waves travel through space and travels through the speed of light.

  3. Transmission and Reception of Radio Waves

  4. DID YOU KNOW THAT: • A sound wave is produced with a frequency of 5 Hz - 20 kHz.

  5. ALSO: • The sound wave is equivalent to a pressure wave traveling through the air.

  6. A microphone converts the sound wave into an electrical signal.

  7. The electrical wave traveling through the microphone wire is analogous to the original sound wave.

  8. What is an electrical wave? • The electrical wave is used to encode or modulate a high-frequency "carrier" radio wave. The carrier wave itself does not include any of the sound information until it has been modulated.

  9. The carrier wave can either be amplitude modulated (AM, top) by the electrical signal, or frequency modulated (FM, bottom).

  10. The signal is transmitted by a radio broadcast tower or antenna.

  11. Your radio contains an antenna to detect the transmitted signal, a tuner to pick out the desired frequency, a demodulator to extract the original sound wave from the transmitted signal, and an amplifier which sends the signal to the speakers. The speakers convert the electrical signal into physical vibrations (sound).

  12. BECAUSE OF RADIO COMMUNICATION: WE CAN BE ABLE TO GET IN TOUCH WITH OUR LOVED ONES AND WE CAN DEVELOP SENSE OF SOCIAL AWARENESS.

  14. SUMMARY: IN A RADIO COMMUNICATION PROCESS, THE RADIO WAVES PLAY A SIGNIFICANT ROLE IN THE TRANSMISSION AND RECEPTION OFMESSAGES. FOR RADIO COMMUNICATION TO OCCUR, THE RADIO STATION IS THE TRANSMITTER AND THE RADIO SET IS THE RECEIVER.
