DE2.3 - Electronics 2

Imperial College London - Dyson School of Design Engineering

DESE50002 - DE2 Electronics 2 (12 Jan to 20 Mar 2026)

Signals, Systems and Control

Professor Peter Y. K. Cheung

LEARNING OUTCOMES

On successful completion of the module, students should be able to:

analyse and inteprete signals in both time and frequency domains;

analyse and interprete signals in both analogue and digital forms;

use Matlab or similar tools to perform analysis of signals and systems;

extract useful information from signals through analysis, filtering and other form of signal conditioning;

understand system behaviour in terms of poles and zeros and perform analysis and prediction of such systems; employ principles of feedback to improve various performance parameters in an electronic system;

analysis simple feedback systems to establish stability in the system;

design and tune a proportional-integral-differential (PID) controller;

implement both signal processing and control algorithms in an standalone, embedded electronic system using real-time programming techniques.
