In practice, systematic sampling is used on account of its simplicity and convenience. It's easy to explain to the people doing the actual work. It can be justified theoretically wherever the population from which units are to be sampled systematically are randomly distributed. It can be used for sampling households, sampling callers on a telephone line, sampling plants along a transect in (say) a field, sampling people passing through customs, and so on.
A systematic error. This may arise because the measuring instrument is not properly calibrated or because there is a bias in recording the results.
Multistage sampling is a form of cluster sampling where instead of using the entire cluster, random samples from each cluster are used. This is typically used when doing opinion polls or surveys.
The sampling level is the size or limit of a population used during a study. This level is used to determine if a particular standard or mandate is being met.
The sampling rate is expressed in units of either "samples per second" or "Hertz (Hz)".

Sampling is the key technique used to digitize analog information. For example, music CDs are produced by sampling live sound at frequent intervals and then digitizing each sample. The term sampling is also used to describe a similar process in digital photography.

The sound recording is crystal clear.
Usually called a 'sample' - when small bits of other works are used in making new songs, it is called 'sampling.'
The term recording refers to a signal that is used to encode something such as a picture or sound that has been recorded.
