What else can I help you with?
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".
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
How does radio communication device work?
A radio communication device works by converting sound waves into electrical signals, which are then modulated onto a carrier wave for transmission. The modulated signal is broadcasted through an antenna, propagating through the air as electromagnetic waves. At the receiving end, another antenna captures these waves, and the device demodulates the signal back into sound waves, allowing for clear audio communication. This process enables two-way communication over varying distances, depending on the device's power and frequency used.
What was radio first used for?
Ship communication.
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
What is a carrier and how does it affect what you hear on the 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.
What is the significance of the side band in the context of radio frequency communication?
The sideband in radio frequency communication is important because it carries the actual information being transmitted, such as voice or data. It is created when a carrier signal is modulated with the input signal, allowing for the transmission of information over the airwaves. The sideband contains the encoded message that is decoded by the receiver, making it a crucial component of radio communication.
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..
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.
How is a carrier wave produced?
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.
Why Need for carrier frequency stability?
Explain the need for carrier frequency stability in radio transmitters?
What is the significance of side band frequency in the field of radio communication?
Sideband frequencies are important in radio communication because they carry the actual information being transmitted. By modulating the carrier signal with the desired audio or data signal, sidebands are created that contain the information to be transmitted. These sidebands are what allow us to hear sound or see data on our radios, making them a crucial component in the process of communication.
