WebFeb 22, 2024 · For example, if the differnce between a correlation of .99 one of .995 is not theoretically interesting, then you probably would not want to do the transformation. On the other hand, if this difference is meaningful and theoretically more important than a difference between .79 and .795 then the transformation makes sense. WebHistory. 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.
