Course purpose

The course teaches fundamental methods in digital signal processing applicable in audio engineering and active noise and vibration. Audio signal processing is applied in both time and frequency domain and is ubiquitous in modern communication systems. The course also gives insight into various approaches for active control, the physics behind these approaches and their implementation.

Schedule
