1. Digital Signal Processor:
A digital signal processor is a dedicated microprocessor whose architecture is optimized for fast processing of mathematically intensive operations such as addition, subtraction, multiplication, and division, especially multiply-and-add (MAC) operations. These chips are typically used in applications that require digitization and high-speed mathematical computation of analog signals, such as audio signals, video signals, control signals, sensor signals, etc. DSP chips are designed to efficiently run digital filter algorithms, Fourier transforms, and other digital signal processing tasks.
2. Digital Signal Processing:
Digital signal processing is a field of technology that involves the use of algorithms to alter or analyze the content or characteristics of analog signals after they have been digitized into digital signals. Digital signal processing can be used to remove noise, extract useful signals, perform signal compression and expansion, and a variety of other signal analysis and modification tasks.
DSP technology is used in a wide range of applications in communications, sound and image processing, radar and sonar signal processing, medical image processing, speech recognition, audio coding, digitized television and multimedia, and other areas that require complex algorithms to process digital signals.
