if the analg to digital transformation is simply too slow and results in information distortion. It could be an audio flutter or movie which includes jagged edges. A filter or super sampling can possibly prevent this.
Distortion caused in analog-to-digital transformation by a too low-rate of data sampling. For sound signals, it often results in flutter (quick improvement in the signal) and, for movie indicators, in stairsteps-like jagged edges (called 'jaggies') that show up on an image of curved or slanted outlines. Treated or subdued by antialiasing methods particularly filtering or super-sampling.
