What is the wool of the carrier?
Waves
The carriers are the progress that have been modified for information transmission, although unmodified waves can also be called carrier. Modification can occur in a number of different ways, such as amplitude modulation methods (AM) and frequency modulation (FM) used for radio transmission. The wool of the carriers are usually sinus waves, but in some cases neinusoid square waves can also be used. It is also possible that the carriers spread like electromagnetic waves or are transmitted through physical media. TV broadcasts of the radio and the air (OTA) are examples of technologies that rely on electromagnetically disseminated supporting waves, while cable television uses a supporting wool that is browsing through a physical data infrastructure. If it is not modified, this sinus wave simply repeats and never changes. On the radio and Television Applications, the amount that oscillates every second every second is what determines the frequency of the station or channel. FM belt in many parts of the world consists of waves of carriers thatThey oscillate between about 88 million and 108 million times every second. This means that a radio station, which broadcasts a frequency of 100 MHz, sends a wool of a carrier that oscillates 100 million times per second.
In order to pass useful information about the support wave, it must be modified in some way. This modification process is usually referred to as modulation and can be applied to the frequency or amplitude of the bearing wool. In the case of frequency modulation, a data signal is used to adjust the carrier frequency. When this happens, the frequency of the carrier with increasing the amplitude of the data signal increases. The amplitude modulation works in Similar, although the amplitude of the carrier is modified to match the amplitude of the data signal.
Waves can be used in a number of different applications. In the case of television broadcasting of the radio and OTA, the carrier spreads in the form of an electromagnetic wave. When such a wave contact an antenna of the receiver's device, D can be dEmodulate for the reconstruction of the original data signal. It is also possible that the bearing wool will be sent by a physical medium, such as a cable television network. In this case, many waves of the carrier with different frequencies can share the same physical cable called frequency division of multiplexing.
