Radio Broadcasting and Communication

Radio broadcasting is transmission of audio by radio waves intended to reach a wide audience.  Electrons move so quick the transmitter, shooting out radio waves. The radio waves travel through the air at the speed of light. As the radio waves hit a receiver, they make electrons vibrate inside which recreate the original signal. Information is carried across space using radio waves.

Answers:

1. Microphone
2. Modulator
3. Antenna
4. Demodulator
5. Amplifier
6. Speaker

Things to Remember:

            As the broadcaster speaks, the sound wave being produced by microphone which is converted to AF signals that will be sent to modulator that will transform the AF signal and RF carrier into modulated carrier wave. The antenna will transmit the modulated carrier wave and will be received by a receiving antenna. The demodulator will transform modulated carrier wave into the AF signal and its energy will be increased with the help of amplifier. The amplified signal will be converted as sound wave again through the speaker.

Verified answer

Answer:

the sound wave is being produced by MICROPHONE w/ch is converted to af signals and sent to MODULATOR that will transform af signal and rfc to modulated carrier wave. ANTENNA transmits the carrier wave and received by "receiving antenna". DEMODULATOR will transform mcw into af signal and its energy will be increased w/ the help of AMPLIFIER. amplified signal will be converted as sw again through SPEAKER.
