Z-transform - Wikipedia
https://en.wikipedia.org/wiki/Z-transformHistory. The basic idea now known as the Z-transform was known to Laplace, and it was re-introduced in 1947 by W. Hurewicz and others as a way to treat sampled-data control systems used with radar. It gives a tractable way to solve linear, constant-coefficient difference equations.It was later dubbed "the z-transform" by Ragazzini and Zadeh in the sampled-data control group at …
