OVERVIEW

Signal processing applications span an immense set of discipines that include communications, space explorations, and medicine just to name a few. In particular, digital signal processing deals with the representation, transformation, and manipulation of signals and the information therein.

LEARNING OUTCOMES

This course aims to provide the basic knowledge on the basic methodologies for signal manipulation, digital signal processing. Particular attention will be given to biomedical applications of each presented techinque. This to provide to the student a view of direct usage of theoretical knowledge 

AIMS AND LEARNING OUTCOMES

This course aims to provide theoretical instruments and practical examples for the treatment of digital signals and data with particular attention to the biomedical applications. The main objective of this teaching course is to give insights of the importance of signal processing techniques and of inferential statistics as fundamental instruments of the biomedical engineer. The application of those techniques will develop specific capabilites of the biomedical engineering student in the usage of those teoretical contecpts tailored to   problems specific of medical-biological contexts.

PREREQUISITES

It is required for the student to have basic understanding of the fundamental elements of system engineering (e.g., Laplace Fourier transforms) and basic descriptive statistics - e.g., hisotgrams, mean and variance

Teaching methods

Frontal lessons with Matlab exercises that students will solve autonomously and deliver through aulaweb-platoform for their evaluaiton at the end of the semestrer.
