# ELEX 3545 - Digital Signal Processing

## Electrical and Computer Engineering Part-time Studies Course

### School of Energy

To support you and your education, BCIT is adapting applied learning in formats appropriate to the unfolding global situation. All PTS classes are being delivered in an online format unless you are notified otherwise.

# Course Details

Introduces the student to Digital Signal Processing techniques. Topics include: continuous and discrete time systems, z-transforms and Fast Fourier Transforms. In addition, the course includes the design and implementation of digital filters. A filter design package such as MatLab is used. The filter designed by the student on the package will be tested on a TMS320C6211 DSK board.

## Prerequisite(s)

ELEX 2120 and ELEX 3305* and MATH 3431* (* may be taken concurrently)
