Module overview
This module introduces the idea of signal analysis, and the mathematical concepts and methods used to classify, transform, and analyse signals. These fundamentals are then applied within then context of control, which is intended to give the students skills an knowledge to apply in many control scenarios - for example PID controllers. The course provides a route into more complex control modules in later years, in terms of both the mathematical theory and the ideas.
