Course description and aims

In discrete time system such as digital signal processing, z-transform is essensial to understand a system behavior and analysis; same as contenious system's Laplace transform. The z-transform is widely apply to the linear time invarient systems. The lecture topics are, discrete time signal and systems, z-transforme and inverse z-transform, z-transforme property, transmission function and frequency response, FIR and IIR filters, s-z transform and system stability.

The aim of this course is to understand z-transform to analize time discrete systems. In linear time invarient systems, time domain and frequency domain basic comprehension will be accomplished.

Student learning outcomes

This course will give students understanding time domain and frequency domain responses of time discrete systems. For analytical method, z-transform is essensial and basic mathematics.

Corresponding educational goals are:
(1) Specialist skills Fundamental specialist skills
(6) Firm fundamental specialist skills on electrical and electronic engineering, including areas such as electromagnetism, circuits, linear systems, and applied mathematics

Keywords

differential equation, linear time invarient system, convolution, z-transform, inverse z-transform, transmission function, frequency response, FIR filter, IIR filter, s-z transform, digital filter, digital signal processing, system stability

Competencies that will be developed

Intercultural skills Communication skills Specialist skills Critical thinking skills Practical and/or problem-solving skills

Class flow

At the beginning of each class, solutions to exercise problems that were assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
