Home theater receivers use Digital Signal Processing for creating soundfields (simulated acoustic environments) and for precise steering of multichannel soundtrack information. When an audio signal is processed and routed in the digital domain, it is less susceptible to signal loss and added distortion.
The processing or modification of digital information, such as audio signals which have been digitally encoded.
A special processor circuit that is designed to perform complex operations on audio waveforms. DSP is used in sound cards, or audio equipment to create sound fields which are electronic or digitally synthesized acoustical environments for audio enhancement, and to create time delays for precise steering of multi-channel Dolby Pro Logic information.
Any signal processing done to an analog audio signal after it has been converted into digital audio.
The processing of control and video signals by digital means as opposed to analogue techniques.
Manipulation of audio or video signals by performing mathematical functions on the digitally encoded signal.
The study of signals in a digital representation and the processing methods of these signals. Since the goal of DSP is usually to measure or filter continuous real-world analog signals, the first step is usually to convert the signal from an analog to a digital form, by using an analog-to-digital converter. Often, the required output signal is another analog output signal, which requires a digital-to-analog converter. (source)
Manipulating an audio signal digitally to create various possible effects at the output. Often refers to artificially generated surround effects derived from and applied to two-channel sources.
Is a level of image correction or enhancement which takes place within a device using a digital computer element. This digital element encodes the information into digital information for the highest level of detail and quality. Cameras with DSP imagers do not necessarily produce "digital video," but they do provide very crisp video images. Quads and multiplexers offering DSP do not necessarily produce "digital video" either, but they do deliver very high resolution and often other dynamic characteristics.
DSP is a powerful processing tool that is currently used primarily to add spatial characteristics to recordings for surround sound.
(DSP) - Describes various digital processes to enhance analog transmission.
processing analog signals in the digital domain: performing mathematical operations on digitized samples of a signal to achieve results -- filtering, phase-shifting -- previously obtainable only by passing an analog signal through special circuits
Mathematical operations performed upon a digitized signal which have the effect of altering the final audio signal. Typical DSP operations include reverb, delay, flanging, phasing, and chorusing. (See "Reverb")
Unique Panasonic digital signal processing technologies deliver true-to-life detail and color, with whiter whites, deeper blacks, and superb rendering of fine details such as individual strands of hair.
Digital Signal Processor; a computer chip that is optimised to carry out common signal-processing arithmetical operations in real-time, and which is generally used to perform operations on audio and video signals, e.g. as in communications and television systems.
Circuits that shape and enhance a signal when it's still in the digital domain. Audio DSP circuits can perform surround sound decoding, create acoustic environments, adjust the bass and treble with incredible precision and even adjust the volume.
the modification of audio signals that have been converted from analog to digital for the purpose of improving the quality of the audio signal in some way. Also often used to reference the microprocessor hardware used to accomplish this objective.
Digital circuits designed to address a broad class of problems in signal reception and analysis that have traditionally been solved using analog components. DSP is used to enhance, analyse, filter, modulate or otherwise digitally manipulate standard analog functions, such as images, sounds, radar pluses and other such signals.
A technique whereby analog signals (representing real-time physical phenomena such as sound or images) are processed into a stream of digital data.
Found often in high-end industrial CCD cameras, digital signal processing involves analog-to-digital conversion of all or part of a standard video signal to enhance/change the resulting signal recovered upon digital-to-analog conversion. Enhancements usually pertain to RGB balancing for more accurate color reproduction.
Audio signal manipulation executed entirely in the digital domain.
Describes the process of using sophisticated mathematical computations and signal processing to pack a lot of information into a digital signal.
Digital signal processing (DSP) is the study of signals in a digital representation and the processing methods of these signals. DSP and analog signal processing are subfields of signal processing. DSP has at least four major subfields: audio signal processing, control engineering, digital image processing and speech processing.
