non-uniform sampling on the unit circle - applications
Uniform sampling is the definite standard as it simplifies not only mathematical derivations but also practical applications. On the other hand, there are some applications (such as array of sensors located in a nonuniform grid) in which taking uniformly distributed samples from a signal of interest is impossible. In such cases nonuniform sampling in either time or space is performed and the usual approach is to convert those nonuniform samples to uniform ones. Then follows the standard operations on those precomputed uniform samples.
