Description
Take for example this free course, Electronic applications. An interactive website with videos and interactive software will show how electronic systems pervade everything we do; review some basic ideas of signal processing, control and communications; and allow you to use a digital filter to remove Gaussian noise from a signal.
Course learning outcomes
After studying this course, you should be able to:
- Understand the mathematical representations and techniques for manipulating of signals in the time and frequency domains
- Explain the application, benefits and limitations of communications, control and signal processing techniques in real world applications
- Select and apply appropriate techniques to the analysis of time-varying signals represented in both the time and frequency domain
- Use a digital filter to remove Gaussian noise from a signal.
