It is a technique that has greatly contributed to the technological advancement of communications and control systems. This paper<br>presents a phase-locked loop tutorial based on a control system, it gives<br>a concise review of basic concepts, the different types of PLLs, linear<br>analysis approaches of analog systems PLL is discussed, furthermore the<br>theoretical analysis of the steady-state error in detail is presented, and its<br>simulations of different phase offset values in C program are presented,<br>and show how the response of the loop changes.</p> ER -
