Abstract

Digital signal processing involves the analysis, modification, and synthesis of signals using digital techniques. Key topics include filtering, Fourier transforms, signal compression, and adaptive algorithms. DSP is essential in communication systems, audio and image processing, biomedical signal analysis, and radar systems.

Human–computer interaction focuses on designing user-friendly interfaces that improve the interaction between humans and digital systems. Technical areas include usability engineering, interface design, cognitive modeling, and user experience (UX) evaluation. HCI plays a vital role in software design, wearable technology, and interactive systems.
