DSP (Digital Signal Processing) is a field of study that focuses on the manipulation of digital signals. These signals can represent various forms of data, such as audio, video, and sensor readings. By using mathematical algorithms, DSP techniques can enhance, filter, or compress these signals, making them more useful for various applications. DSP is widely used in many technologies, including smartphones, audio equipment, and medical devices. For example, in music production, DSP helps improve sound quality by removing noise or adjusting frequencies. Overall, DSP plays a crucial role in modern electronics and communication systems.
