Electrical and Electronic Engineering Final Year Topic: Investigation of Digital Phase-Locked Loop Response

This Electrical and Electronic Engineering final year project examines tracking phase changes in a noisy synthetic reference signal, with a bounded circuit, model or measurement procedure and explicitly defined evaluation quantities.

Why choose this project topic?

The project focuses on tracking phase changes in a noisy synthetic reference signal, making the engineering decision visible through measurable behaviour. Comparing lock time, phase error and loss-of-lock rate provides material for waveforms, calculations and a reasoned discussion of the trade-offs behind the selected design.

How do the selected circuit, control or measurement choices affect lock time, phase error and loss-of-lock rate when tracking phase changes in a noisy synthetic reference signal?

Agree the available approved equipment or simulation platform, operating range and comparison method for tracking phase changes in a noisy synthetic reference signal with your supervisor.

Proposed project objectives

  1. 01Specify the operating limits, assumptions and reference conditions for tracking phase changes in a noisy synthetic reference signal.
  2. 02Implement a bounded digital loop, compare bandwidth settings and test frequency steps and phase noise with known ground truth.
  3. 03Evaluate lock time, phase error and loss-of-lock rate and explain model or measurement uncertainty.

A suggested research approach

Implement a bounded digital loop, compare bandwidth settings and test frequency steps and phase noise with known ground truth. Obtain supervisor approval for equipment and operating limits, and use simulation whenever the physical setup is unavailable or unsafe. Record units, instrument settings and repeated observations before comparing lock time, phase error and loss-of-lock rate with a defined reference.

What you will need

  • Synthetic reference signals
  • DSP simulation environment
  • Documented loop equations

Keep your project scope clear

Simulation does not establish compliance with any commercial communication standard.
