An electromagnetic wave that can be modulated, either in frequency, amplitude or phase, to transmit speech, music, images, or other signals
A high-frequency electromagnetic wave capable of being modulated to transmit a signal of lower frequency
{i} electromagnetic wave that can be modulated to transmit a signal from the transmitter to the receiver
Carrier waves are used to carry information from transmitter to receiver The carrier wave will be radio or microwave frequency There are two methods of using the carrier wave to carry information - amplitude modulation and frequency modulation In radio transmissions for example, the carrier is of a much higher frequency than the audio wave which is to be transmitted The higher the frequency of the carrier, the higher the quality of the transmitted signal
An electromagnetic wave that is emitted by a radio transmitter in order to carry information The information is superimposed onto the carrier by making small changes to either its amplitude or its frequency
The radio frequency wave generated at a transmitting station for the purpose of carrying the modulated or audio frequency
A high-frequency wave that can be sent through the air and is modulated by a lower-frequency wave containing information 14 6
An electromagnetic wave that can be modulated, as in frequency, amplitude, or phase, to transmit speech, music, images, or other signals
A wave generated at a point in the transmitting system and modulated by the signal
Transmitted energy which is modulated in order to carry information Usually, it is in the form of a radio-frequency sine wave, modulated either in amplitude or in frequency
Transmitted energy which is modulated in order to carry information Usually, it is in the form of a radio- frequency sine wave, modulated either in amplitude or in frequency
