Decreasing the sampling rate is known as decimation. Antoniou, Andreas (2006). Digital Signal Processing. McGraw-Hill. p. 830. ISBN 0-07-145424-1. Decimators can be used to reduce the sampling frequency, whereas interpolators can be used to increase it. Milic, Ljiljana (2009). Multirate Filtering for Digital Signal Processing.

Music plagiarism is the use or close imitation of another author's music while representing it as one's own original work.Plagiarism in music now occurs in two contexts—with a musical idea (that is, a melody or motif) or sampling (taking a portion of one sound recording and reusing it in a different song).

In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave to a sequence of "samples".

The bias of the sample cannot be measured. Therefore, inferences based on convenience sampling ...
