amplitúdómodulációval
Amplitúdómodulációval, often abbreviated as AM, is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. It works by varying the amplitude, or strength, of the carrier wave in proportion to the signal being transmitted. Imagine a constant wave, the carrier, and then you're making its peaks and troughs taller or shorter to represent the information.
In a typical AM system, a high-frequency carrier wave is combined with a lower-frequency message signal. The
At the receiving end, a demodulator is used to extract the original message signal from the modulated
