Chapter five: Discrete models and z-transforms

These quizzes link to chapter five. They on the theme of discrete time linear models, for example:

yk+a1yk-1 + ...+ anyk-n = b1uk-1 + ...+ bnuk-n

where y(t) is the output, u(t) the input and ai, bi are model parameters. The subscript 'k' denotes the sampling index.

Core skills are things such as:

  • What do I mean by a discrete model/signal and how do I find a discrete mathematical model representation of a real physical system?

  • How do such systems behave and how does the behaviour link to the model parameters?

  • Are there generic analysis tools that help with understanding?

It is implicit that students have core competence in some mathematical topics such as polynomials, roots, complex numbers, exponentials and Laplace.
