How are radio television signals added to EM radio wave?
The process of adding information onto a bare radio wave is called "modulation". It means changing something on the wave ... either its amplitude, frequency, or phase, or actually turning it on and off ... according to a pattern that the transmitting person and the receiving person have worked out and agreed to, so that when the transmitting person makes changes to the wave, the receiving person can figure out what those changes mean.
What does radio stand for?
It is a shortened form of radiotelegraph - apparatus for transmitting or receiving radio broadcasts. Derived from Radiophone and Radiotelography, words coined in the 1890's
What is the difference between a radio in a car and a radio in an aircraft?
Car radios are for receiving music and entertainment programs. Most aircraft will not have this type of radio. They will only have a 2 way transmitting and receiving radio for communicating with airports and other aircraft.
How do you describe about full duplux transmission?
Full duplex is when two frequencies are used for stations to transmit to and receive transmissions from each other. A station will transmit on one frequency, while receiving on a different frequency. This is often accomplished through the use of repeater towers. Radiotelephones, cellular telephones, and some two way systems used in businesses, state provided services, and amateur radio are examples of this.
Do you need a shortwave radio license to just listen in USA?
No. Except for brief periods during wartime, radio receiving equipment has never been regulated. Only transmitting equipment is regulated, for the purpose of keeping things orderly enough so that no transmitter will interfere with the signals of another one. (Personally, I think some receiving equipment should be regulated, specifically speed radar detectors. But that's just my opinion; I could be wrong.)
What term is used describing the transmitting of immunodeficiency virus?
Transmission is caused by the host (the person with the disease) and contraction is the term for the person receiving the disease.
What is mien by carrier frequency?
High range of frequency that carries the message signals in transmission of data.after receiving the signals, the detector seperate the message and carrier .
What is skywave propagation?
the propagation in which transmission and receiving of signals takesplace through the sky waves which having the lower frequency
What type of energy transfers information from a radio station to the radio?
RF stands for Radio Frequency, magnetic waves radiate out of the transmitting antenna and are picked up or recovered by the receiving antenna at the receiver.
What are the elements of radio communication system?
There are many elements of a radio communication system. These elements include a transmitter, radio frequency oscillator, modulator, transmitting ariel, receiving ariel, demodulator, and amplifier.
What is the name of the gap between the transmitting and receiving neurons?

When was Receiving Transmission created?
Receiving Transmission was created in 2004.
How does a bluetooth operate with no wires?
The way bluetooth is able to operate with no wires is by transmitting radio frequency signals to a persons cellphone when receiving a phone call and because of this bluetooth can manage up to 3 Mbps.
What are the Four primary technologies in which wireless lans uses in transmitting and receiving data?
a. Direct sequence spread spectrum (DSSS). b. Frequency hopping spread spectrum (FHSS). c. Infrared d. Orthogonal frequency division multiplexing(OFDM)
What is the difference between transmitting and receiving antenna?
There is no difference between the two.
