The star transform, or starred transform is a discrete-time variation of the Laplace transform that represents an ideal sampler with period of time T. The star transform is similar to the Z transform with a simple change of variables, but the star transform explicitly identifies each sample in terms of the sampling period (T), while the Z transform only refers to each sample by integer index value.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The star transform, or starred transform is a discrete-time variation of the Laplace transform that represents an ideal sampler with period of time T. The star transform is similar to the Z transform with a simple change of variables, but the star transform explicitly identifies each sample in terms of the sampling period (T), while the Z transform only refers to each sample by integer index value. The star transform is so named because it is frequently represented by an asterisk or "star" in the notation. The inverse star transform represents a signal that has been sampled at interval T. The inverse star transform is not the original signal, x(t), but is instead a sampled version of the original signal. The following shows the relationship between the various representations: x(t) rightarrow X^ (s) rightarrow x^ (t)
