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 ...
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.
An L7A1045 DSP chip, as used in several Akai samplers and the Hyper Neo Geo 64 arcade board The NeXTcube from 1990 had a Motorola 68040 (25 MHz) and a digital signal processor Motorola 56001 with 25 MHz which was directly accessible via an interface.

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 ...
In digital signal processing (DSP), a normalized frequency is a ratio of a variable frequency and a constant frequency associated with a system (such as a sampling rate, ). Some software applications require normalized inputs and produce normalized outputs, which can be re-scaled to physical units when necessary.
The output filter removes the high-frequency switching components of the PWM signal and reconstructs audio information that the speaker can use. DSP-based amplifiers that generate a PWM signal directly from a digital audio signal (e. g. SPDIF) either use a counter to time the pulse length [5] or implement a digital equivalent of the triangle ...
The Roland Micro Cube, left, a small and portable digital modeling amplifier. Digital amp modelers Standalone modeling devices such as the Line 6 POD and Fractal Axe-FX digitize the input signal and use a DSP, a dedicated microprocessor, to process the signal with digital computation, attempting to achieve the sound of expensive professional amplifiers in a much less costly and more compact ...
