Phase Shift vs Phase Shift Keying

  1. Dec 7, 2012 #1
    Respected Friends !

    I want to know the relationship between Phase Shift (PS) and Phase Shift Keying (PSK). Please can anyone help me.

    Thank You

    Welcome to the PF.

    Phase shift is just a general term, unless you've seen differently in some context. PSK is a form of modulation, used to transfer information over a communication channel. What reading have you done to learn about PSK?

    Thank You for Reply Friend.

    I only know that PSK is a used for digital to analog modulation and according to different bits they adjust different phase like for 0 Phase 0, for bit 1 Phase 180 etc

    I don't know about the relationship between Phase shift and Phase Shift keying, Can you please help me in detail.

    Can you tell me from where I can get detail about it.

    You can read introductory material about PSK here:


    The term "phase shift" in general just means a signal whose phase is shifting by some amount and in some direction over time:
