modulációknál

Modulációknál refers to the plural form of moduláció in Hungarian, which translates to modulation in English. In telecommunications and signal processing, modulation is a process used to encode information onto a carrier signal. This is typically achieved by varying one or more properties of the carrier wave, such as its amplitude, frequency, or phase, in accordance with the waveform of the information signal.

There are various types of modulation techniques. Amplitude modulation (AM) varies the amplitude of the carrier signal, while frequency modulation (FM) varies its frequency. Phase modulation (PM) alters the phase of the carrier wave. Digital modulation schemes, such as Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK), are used to transmit digital data. These methods are fundamental to modern communication systems, enabling the transmission of voice, data, and video over long distances. The choice of modulation technique depends on factors such as the desired data rate, bandwidth limitations, and noise immunity. Modulation is a key process in radio broadcasting, television, mobile phone communications, and many other wireless technologies.
