Phase Shift vs Phase Shift Keying

AI Thread Summary
Phase Shift (PS) refers to the change in phase of a signal over time, while Phase Shift Keying (PSK) is a specific modulation technique that uses phase shifts to encode data for transmission. PSK adjusts the phase of a signal based on the digital bits being transmitted, such as using a phase of 0 for a bit 0 and 180 degrees for a bit 1. The discussion highlights the need for further reading to understand the relationship between these concepts, with suggestions for introductory resources. Overall, the conversation emphasizes the importance of understanding both terms in the context of communication systems. The user expresses gratitude for the information and indicates their study on the topic is now complete.

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:
