A Digital Signal Processor (DSP) is a specialized microprocessor designed to efficiently process digital signals. These signals can include audio, video, and other data types that require real-time processing. DSPs are optimized for tasks such as filtering, compression, and modulation, making them essential in various applications like telecommunications, audio processing, and image analysis. DSPs operate using mathematical algorithms to manipulate data quickly and accurately. They are commonly found in devices such as smartphones, digital cameras, and audio equipment. By handling complex calculations at high speeds, DSPs enhance the performance and quality of digital media and communication systems.
