Phase Shift vs Phase Shift Keying

Click For Summary
SUMMARY

Phase Shift (PS) refers to the general concept of a signal's phase changing over time, while Phase Shift Keying (PSK) is a specific modulation technique used for digital to analog conversion. In PSK, different phases represent different bits, such as 0 Phase 0 for bit 0 and 180 Phase for bit 1. Understanding the relationship between these two concepts is crucial for grasping digital communication techniques. For further reading, introductory materials on PSK and phase shifts are available on Wikipedia.

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:
