Q:

What is a DSP?

A:

Quick Answer

A DSP is a digital signal processor. It is a compilation of techniques used to improve analog signals after the conversion to digital. Data compression is often used in the improvement stage, and the programmable nature of DSP encompasses manipulation of sounds, images and video.

Full Answer

The process of improvement begins when an analog-to-digital converter is used, transforming the signal into digital values that can be mathematically manipulated. The equipment used to do this ranges from microprocessors to application-specific integrated circuits. Field-programmable gate arrays and digital signal controllers are used for more robust industrial applications. Signal-sampling of the target is performed in the time and spatial domains for signal processing.
