A mathematical or signal processing technique that reverses the effects of convolution, separating mixed or blended signals back into their original components.
From prefix 'de-' (to reverse) + 'convolution' (from Latin 'convolvere', to roll together). A technical term that emerged in 20th-century signal processing and mathematics.
Deconvolution is the mathematical magic behind sharpening blurry photographs and clearing up distorted audio—scientists essentially teach computers to reverse time and 'unmix' signals that have been blended together.
