Alapsávjel

Alapsávjel is a Hungarian term that translates to "base band" in English. It refers to the frequency band that carries the original, unmodulated signal in telecommunications and audio systems. This band contains the fundamental frequencies of the information being transmitted, before any carrier wave is applied or any compression or modification techniques are employed.

In the context of audio, the alapsávjel represents the full range of audible frequencies produced by an instrument or voice. When audio signals are transmitted or recorded, they are often modulated onto a carrier wave or processed to reduce bandwidth or storage space. The alapsávjel is the source material from which these processed signals are derived. Maintaining the integrity of the alapsávjel is crucial for high-fidelity reproduction.

In telecommunications, the alapsávjel is the raw signal that contains the information to be sent. This signal is then typically modulated onto a higher frequency carrier wave for efficient transmission over long distances. The process of modulation shifts the alapsávjel to a different frequency range suitable for radio waves or other transmission media. Demodulation is the reverse process, where the original alapsávjel is recovered from the received modulated signal. The concept of alapsávjel is fundamental to understanding how signals are processed and transmitted.
