Sound.More informationAfter a modulated carrier signal has been received through the radio's aerial, the radio de-modulates it to release the live sound as picked-up from microphones in the radio studio (or was taken from recordings), which was then used to modulate the carrier signal at the transmitter.De-modulation that is done by a radio receiver can be described very simply as "removing the carrier signal to produce the sound".
Frequency Modulation must have a carrier whereby the frequency can be modulated by the signal
Ship communication.
Shortwave radio is used for broadcasting of voice and music to shortwave listeners, and long-distance communication to ships and aircraft, or to remote areas out of reach of wired communication or other radio services. Additionally, it is used for two-way international communication by amateur radio enthusiasts for hobby, educational and emergency purposes.
Mobile radio communication is performed by utilizing a battery-powered radio in the field in order to transmit messages to a fixed home base receiver.
They used airplanes, zepline, observation ballon, radio, and carrier pegions
radio
A carrier is a high-frequency signal that carries information on a radio wave. The carrier frequency is modulated to encode audio signals, which are then transmitted and decoded by the radio receiver to produce sound. The carrier frequency determines the station you're tuning into on the radio.
Mass communication is a means of transmitting or relaying information with the use of mass media like newspapers, televisions and radio by distributing information to a large group of people. Mass communication has five functions namely for: interpretation, lineage, transmission of values, surveillance, and entertainment.
Because in radio communication a signal is specified by its frequency, In AM the carrier frequency is fixed.. we cant limit or manipulate it as it will might switch us to another carrier in the atmosphere... manipulating however amplitude (as in FM) doesn't switch us to another channel... so remember in radio communication signal is specified by its frequency whether FM or AM..
False.
False.
A carrier wave is produced by an electronic oscillator that generates a steady waveform at a specific frequency. This waveform serves as the base signal on which information is modulated for transmission in communication systems like radio and television. The carrier wave's frequency determines the bandwidth and reception quality of the transmitted signal.
