Hordozójelének

Hordozójelének is a Hungarian term that translates to "carrier signal" in English. It refers to a modulated wave used to transmit information. In radio communication, for example, a hordozójelének is the high-frequency electromagnetic wave that is altered (modulated) by a lower-frequency signal containing the actual message, such as voice or data. This modulation allows the information to be propagated over long distances via radio waves.

The concept of a hordozójelének is fundamental to many communication technologies, including broadcasting, wireless networking, and telecommunications. Without a carrier signal, the information-carrying signal would be too weak and short-ranged to be useful for transmission. The carrier signal provides the "vehicle" for the information, enabling it to travel through a medium like air or space.

Different types of modulation techniques, such as amplitude modulation (AM) and frequency modulation (FM), are used to encode information onto the hordozójelének. The choice of modulation depends on factors like the desired bandwidth, resistance to noise, and the specific application. The receiver then demodulates the signal, extracting the original information from the carrier.
