Phase-shift keying (PSK) is a digital modulation technique that encodes data by varying the phase of a carrier wave. This method allows for the transmission of information by shifting the phase of the signal, which can represent different symbols or bits. It is widely used in communication systems due to its robustness against noise and interference, making it suitable for various applications, including digital communication protocols.
congrats on reading the definition of Phase-Shift Keying. now let's actually learn it.
