sávtartomány

The term sávtartomány, originating from Hungarian, translates to "band domain" or "frequency band range" in English. It refers to a specific, continuous range of frequencies within the electromagnetic spectrum or a signal. In telecommunications, this concept is crucial for allocating and managing radio frequencies. Different applications, such as broadcasting, mobile communication, and satellite services, are assigned distinct sávtartományok to prevent interference.

The utilization of a sávtartomány is often governed by regulatory bodies like the International Telecommunication Union (ITU) or national telecommunications authorities. These organizations define the boundaries and permissible uses for various frequency bands. For example, the VHF (Very High Frequency) sávtartomány typically spans from 30 MHz to 300 MHz, encompassing frequencies used for FM radio and television broadcasting. Similarly, the UHF (Ultra High Frequency) sávtartomány, from 300 MHz to 3 GHz, is used for a wider array of services including mobile phones and Wi-Fi.

Understanding the sávtartomány is fundamental in the design and implementation of communication systems. Engineers must select appropriate components and modulation techniques that operate effectively within the allocated frequency band. The concept also plays a role in signal processing, where filters are designed to isolate or remove signals within specific frequency ranges, thereby defining a particular sávtartomány for analysis or transmission. The efficient allocation and use of these frequency bands are vital for the functioning of modern wireless technologies.
