A Digital Signal Processor (DSP) is a specialized microprocessor designed to perform specific tasks related to signal processing, such as filtering, modulation, demodulation, compression, and decompression. DSP is commonly used in audio and video signal processing, telecommunications, and digital image processing. DSP is a highly specialized skill that requires knowledge of programming, mathematics, signal processing algorithms, and specialized hardware. DSP technology has revolutionized the way signals are processed, making it possible to transmit, store, and manipulate complex signals in real-time.
