Digitaalmodulatsioonid
Digitaalmodulatsioonid refer to the process of encoding digital information onto an analog carrier signal. This is a fundamental technique in digital communication systems, allowing data to be transmitted over channels originally designed for analog signals, such as radio waves or telephone lines. The core idea is to vary one or more properties of the carrier wave, such as its amplitude, frequency, or phase, in accordance with the digital data bits (0s and 1s).
Common digital modulation techniques include Amplitude Shift Keying (ASK), where the amplitude of the carrier wave
The choice of modulation scheme depends on factors such as the desired data rate, the quality of
