Digital Signal Processing (DSP) is a field of study that focuses on the manipulation of signals using digital techniques. It involves the conversion of analog signals into digital form, allowing for various operations such as filtering, compression, and enhancement. DSP is widely used in applications like audio processing, image processing, and telecommunications. The primary goal of DSP is to improve the quality and efficiency of signal transmission and reception. By employing algorithms and mathematical models, DSP enables the extraction of meaningful information from raw data. This technology plays a crucial role in devices such as smartphones, hearing aids, and radar systems.
