Advantages: it improves frequency stability. phase modulation n demodulation is easy as compared to frequency modulation.
I don't know of any disadvantages only advantages! no computer or any digital system can work without it and you can transfer it in serial or parallel
8 phase shift keying is a complex form of digital modulation by altering a sine wave and a cosine wave: shifting their phase. The best explanations I have found so far can be found at...
