What is the use of radio communication?
it is used for the communication
What does a radio transform waves into?
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".
What was radio first used for?
Ship communication.
How do you send a digital radio signal to a FM radio?
Frequency Modulation must have a carrier whereby the frequency can be modulated by the signal
What are short radio waves used for?
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.
What is mobile radio communication?
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.
How did communication change throughout World War 1?
They used airplanes, zepline, observation ballon, radio, and carrier pegions
Which communication system best describes well suited for on the move and allows maintenance of command and control functions?
radio
Functions of mass communication?
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.
In an FM receiver you use amplitude limiter but in am receiver you do not use frequency limiterexplain?
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..
What is the use of radio communication?
it is used for the communication
To get information into its carrier wave every radio station has to amplify the carrier wave.?
False.
To get information into its carrier wave every radio station has to amplify the carrier wave?
False.
Why Need for carrier frequency stability?
Explain the need for carrier frequency stability in radio transmitters?

What is the modular of radio transmitters?
generates carrier waves
What is carrier frequency?
A carrier frequency is a single radio frequency with steady amplitude. Alone, it would sound like silence on a receiver. This is the frequency that a radio receiver is tuned into. To be of use in communication, this carrier wave has to be changed in time with another signal (usually audio), called 'Modulation' It can be turned on and off using a Morse key. It can be changed by shifting the frequency, FM. It can be changed by varying the amplitude, AM. It can be changed by adding or subtracting audio to the carrier. Single Side Band. It can have data applied by shifting between two carrier frequencies. FSK. (Frequency shift keying.) It's called a carrier, because it is the carrier of information without necessarily being the information itself.
