Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space ...
Many DSP applications have constraints on latency; that is, for the system to work, the DSP operation must be completed within some fixed time, and deferred (or batch) processing is not viable. Most general-purpose microprocessors and operating systems can execute DSP algorithms successfully, but are not suitable for use in portable devices ...
In order to accelerate multidimensional DSP computations, using dedicated supercomputers or cluster computers is required in some circumstances, e.g., weather forecasting and military radars. Nevertheless, using supercomputers designated to simply perform DSP operations takes considerable money cost and energy consumption.
MOS integrated circuit technology was the basis for the first single-chip microprocessors and microcontrollers in the early 1970s, [35] and then the first single-chip digital signal processor (DSP) chips in the late 1970s. [36] [37] DSP chips have since been widely used in digital image processing. [36]

A digital signal controller (DSC) is a hybrid of microcontrollers and digital signal processors (DSPs). Like microcontrollers, DSCs have fast interrupt responses, offer control-oriented peripherals like PWMs and watchdog timers, and are usually programmed using the C programming language, although they can be programmed using the device's native assembly language.
In digital signal processing, downsampling, compression, and decimation are terms associated with the process of resampling in a multi-rate digital signal processing system.
Digital Hybrid systems use an analog FM transmission scheme in combination with digital signal processing (DSP) to enhance the system's audio. Using DSP allows the use of digital techniques impossible in the analog domain such as predictive algorithms, thus achieving a flatter frequency response in the audio spectrum and also further reducing ...
