Digital Signal Processing (DSP) refers to the manipulation of signals that are in a digital format. This technology is used to analyze, modify, and synthesize signals such as audio, video, and sensor data. DSP techniques can improve the quality of these signals, making them clearer and more useful for various applications, including telecommunications and multimedia. DSP is widely used in devices like smartphones, digital cameras, and audio equipment. It enables features such as noise reduction, image enhancement, and speech recognition. By converting analog signals into digital form, DSP allows for more efficient processing and storage, leading to better performance in modern technology.
