The Department of Signal Processing and Acoustics contributes to the common Bachelor programmes of the School of Electrical Engineering, contribute arranging the Master's Programme in Computer, Communication and Information Sciences, especially majors Acoustics and Audio Technology and Speech and Language Processing. We also provide post-graduate education through all of our research groups, as can be seen in our Doctoral dissertations.

Aalto Bachelor's Programme in Science and Technology - Digital Systems and Design

Digital Systems and Design educates specialists in various fields of digital systems. This major gives you competence in engineering design, as well as project planning and management, employing tools from embedded systems, control theory, and signal processing.
