demodulatsioonina
Demodulation is a process used in telecommunications and signal processing to extract the original information-bearing signal from a modulated carrier wave. This is achieved by reversing the modulation process that was applied at the transmitter. Demodulation is a crucial step in the reception of signals, enabling the recovery of the original data or information.
There are several types of demodulation techniques, each corresponding to a specific type of modulation used
1. Amplitude Demodulation (AM): Used to demodulate amplitude-modulated signals. This involves rectifying the signal and filtering
2. Frequency Demodulation (FM): Used to demodulate frequency-modulated signals. This technique involves using a frequency discriminator
3. Phase Demodulation (PM): Used to demodulate phase-modulated signals. This involves measuring the phase difference between
4. Quadrature Amplitude Modulation (QAM) Demodulation: Used to demodulate signals that have been modulated using QAM.
Demodulation is essential in various applications, including radio broadcasting, television broadcasting, satellite communications, and wireless data
