Hordozójelbl

Hordozójelbl is a term of Hungarian origin that translates roughly to "carrier signal." In telecommunications and signal processing, it refers to a fundamental wave that is modulated to carry information. This carrier wave itself typically possesses a constant frequency, amplitude, and phase. The information, whether it be audio, video, or data, is superimposed onto this carrier wave through a process called modulation.

The purpose of a carrier signal is to enable the transmission of information over a medium, such as airwaves or cables. By using a carrier wave, signals can be efficiently transmitted over long distances and can be separated from other signals. Different carrier frequencies are assigned to different communication channels, allowing multiple transmissions to occur simultaneously without interference.

Common examples of modulation techniques used with carrier signals include Amplitude Modulation (AM), Frequency Modulation (FM), and Phase Modulation (PM). In AM, the amplitude of the carrier wave is varied in accordance with the information signal. In FM, the frequency of the carrier wave is varied, and in PM, the phase of the carrier wave is altered. The choice of modulation technique depends on various factors, including the desired transmission quality, bandwidth efficiency, and resistance to noise. The concept of the hordozójelbl is central to radio broadcasting, television transmission, mobile communication, and many other wireless technologies.
