középfrekvencia

Középfrekvencia, meaning "medium frequency" in Hungarian, refers to a range of radio frequencies. While the exact boundaries can vary depending on the specific context or standard, it generally encompasses frequencies between approximately 300 kHz and 3 MHz. This band is part of the broader radio spectrum used for various communication purposes.

In some applications, középfrekvencia is associated with AM broadcasting, where amplitude modulation is employed to transmit audio signals. These frequencies are capable of long-distance propagation, particularly at night, due to ionospheric reflection. Historically, középfrekvencia played a significant role in international radio communication and maritime navigation.

The characteristics of középfrekvencia, such as its propagation patterns and bandwidth capabilities, make it suitable for certain types of transmissions. However, its use is also subject to regulations and allocations by international bodies to prevent interference between different services. The technologies and specific applications utilizing this frequency range continue to evolve.
